-// A `Directory` represents a directory node in a file tree, containing zero or

-// [DirectoryNodes][build.bazel.remote.execution.v2.DirectoryNode] and
-// [SymlinkNodes][build.bazel.remote.execution.v2.SymlinkNode].
-// Each `Node` contains its name in the directory, either the digest of its
-// content (either a file blob or a `Directory` proto) or a symlink target, as
-// well as possibly some metadata about the file or directory.
-//
-// In order to ensure that two equivalent directory trees hash to the same
-// value, the following restrictions MUST be obeyed when constructing a
-// a `Directory`:
-//
-// * Every child in the directory must have a path of exactly one segment.
-//   Multiple levels of directory hierarchy may not be collapsed.
-// * Each child in the directory must have a unique path segment (file name).
-//   Note that while the API itself is case-sensitive, the environment where
-//   the Action is executed may or may not be case-sensitive. That is, it is
-//   legal to call the API with a Directory that has both "Foo" and "foo" as
-//   children, but the Action may be rejected by the remote system upon
-//   execution.
-// * The files, directories and symlinks in the directory must each be sorted
-//   in lexicographical order by path. The path strings must be sorted by code
-//   point, equivalently, by UTF-8 bytes.
-//
-// A `Directory` that obeys the restrictions is said to be in canonical form.
-//
-// As an example, the following could be used for a file named `bar` and a
-// directory named `foo` with an executable file named `baz` (hashes shortened

-// A content digest. A digest for a given blob consists of the size of the blob
-// and its hash. The hash algorithm to use is defined by the server, but servers
-// SHOULD use SHA-256.
-//
-// The size is considered to be an integral part of the digest and cannot be
-// separated. That is, even if the `hash` field is correctly specified but
-// `size_bytes` is not, the server MUST reject the request.
-//
-// The reason for including the size in the digest is as follows: in a great
-// many cases, the server needs to know the size of the blob it is about to work
-// with prior to starting an operation with it, such as flattening Merkle tree
-// structures or streaming it to a worker. Technically, the server could
-// implement a separate metadata store, but this results in a significantly more
-// complicated implementation as opposed to having the client specify the size
-// up-front (or storing the size along with the digest in every message where
-// digests are embedded). This does mean that the API leaks some implementation
-// details of (what we consider to be) a reasonable server implementation, but
-// we consider this to be a worthwhile tradeoff.
-//
-// When a `Digest` is used to refer to a proto message, it always refers to the
-// message in binary encoded form. To ensure consistent hashing, clients and
-// servers MUST ensure that they serialize messages according to the following
-// rules, even if there are alternate valid encodings for the same message:
-//
-// * Fields are serialized in tag order.
-// * There are no unknown fields.
-// * There are no duplicate fields.
-// * Fields are serialized according to the default semantics for their type.
-//
-// Most protocol buffer implementations will always follow these rules when
-// serializing, but care should be taken to avoid shortcuts. For instance,
-// concatenating two messages to merge them may produce duplicate fields.

-  //
-  // The input `Action`'s fields MUST meet the various canonicalization

-  // the same digest as other logically equivalent `Action`s. The server MAY
-  // enforce the requirements and return errors if a non-canonical input is

-// Most of the binary data stored in the CAS is opaque to the execution engine,
-// and is only used as a communication medium. In order to build an
-// [Action][build.bazel.remote.execution.v2.Action],
-// however, the client will need to also upload the
-// [Command][build.bazel.remote.execution.v2.Command] and input root
-// [Directory][build.bazel.remote.execution.v2.Directory] for the Action.
-// The Command and Directory messages must be marshalled to wire format and then
-// uploaded under the hash as with any other piece of content. In practice, the
-// input root directory is likely to refer to other Directories in its
-// hierarchy, which must also each be uploaded on their own.
-//
-// For small file uploads the client should group them together and call
-// [BatchUpdateBlobs][build.bazel.remote.execution.v2.ContentAddressableStorage.BatchUpdateBlobs].
-// For large uploads, the client must use the
-// [Write method][google.bytestream.ByteStream.Write] of the ByteStream API. The
-// `resource_name` is `{instance_name}/uploads/{uuid}/blobs/{hash}/{size}`,
-// where `instance_name` is as described in the next paragraph, `uuid` is a
-// version 4 UUID generated by the client, and `hash` and `size` are the
-// [Digest][build.bazel.remote.execution.v2.Digest] of the blob. The
-// `uuid` is used only to avoid collisions when multiple clients try to upload
-// the same file (or the same client tries to upload the file multiple times at
-// once on different threads), so the client MAY reuse the `uuid` for uploading
-// different blobs. The `resource_name` may optionally have a trailing filename
-// (or other metadata) for a client to use if it is storing URLs, as in
-// `{instance}/uploads/{uuid}/blobs/{hash}/{size}/foo/bar/baz.cc`. Anything
-// after the `size` is ignored.
-//
-// A single server MAY support multiple instances of the execution system, each
-// with their own workers, storage, cache, etc. The exact relationship between
-// instances is up to the server. If the server does, then the `instance_name`
-// is an identifier, possibly containing multiple path segments, used to
-// distinguish between the various instances on the server, in a manner defined
-// by the server. For servers which do not support multiple instances, then the
-// `instance_name` is the empty path and the leading slash is omitted, so that
-// the `resource_name` becomes `uploads/{uuid}/blobs/{hash}/{size}`.
-// To simplify parsing, a path segment cannot equal any of the following
-// keywords: `blobs`, `uploads`, `actions`, `actionResults`, `operations` and
-// `capabilities`.
-//
-// When attempting an upload, if another client has already completed the upload
-// (which may occur in the middle of a single upload if another client uploads
-// the same blob concurrently), the request will terminate immediately with
-// a response whose `committed_size` is the full size of the uploaded file
-// (regardless of how much data was transmitted by the client). If the client
-// completes the upload but the
-// [Digest][build.bazel.remote.execution.v2.Digest] does not match, an
-// `INVALID_ARGUMENT` error will be returned. In either case, the client should
-// not attempt to retry the upload.
-//
-// For downloading blobs, the client must use the
-// [Read method][google.bytestream.ByteStream.Read] of the ByteStream API, with
-// a `resource_name` of `"{instance_name}/blobs/{hash}/{size}"`, where
-// `instance_name` is the instance name (see above), and `hash` and `size` are
-// the [Digest][build.bazel.remote.execution.v2.Digest] of the blob.
-//
-// The lifetime of entries in the CAS is implementation specific, but it SHOULD
-// be long enough to allow for newly-added and recently looked-up entries to be
-// used in subsequent calls (e.g. to
-// [Execute][build.bazel.remote.execution.v2.Execution.Execute]).

-// well as possibly some metadata about the file or directory.
-//
-// In order to ensure that two equivalent directory trees hash to the same
-// value, the following restrictions MUST be obeyed when constructing a
-// a `Directory`:
-//
-// * Every child in the directory must have a path of exactly one segment.
-//   Multiple levels of directory hierarchy may not be collapsed.
-// * Each child in the directory must have a unique path segment (file name).
-//   Note that while the API itself is case-sensitive, the environment where
-//   the Action is executed may or may not be case-sensitive. That is, it is
-//   legal to call the API with a Directory that has both "Foo" and "foo" as
-//   children, but the Action may be rejected by the remote system upon
-//   execution.
-// * The files, directories and symlinks in the directory must each be sorted
-//   in lexicographical order by path. The path strings must be sorted by code
-//   point, equivalently, by UTF-8 bytes.
-//
-// A `Directory` that obeys the restrictions is said to be in canonical form.
-//
-// As an example, the following could be used for a file named `bar` and a
-// directory named `foo` with an executable file named `baz` (hashes shortened
-// for readability):
-//
-// ```json
-// // (Directory proto)

-// many cases, the server needs to know the size of the blob it is about to work
