| gRPC Support | 
 | === | 
 |  | 
 | This directory contains the interface and implementation of the API to use | 
 | an external network stack from gRPC. The implementation is essentially a thin | 
 | wrapper around net::BidirectionalStream. The API specifies that the caller to | 
 | gRPC will pass in an opaque binary blob (stream_engine) that can be used to | 
 | created binary streams. In Chromium, this binary blob is a | 
 | net::URLRequestContextGetter, which is used by grpc_support::BidirectionalStream | 
 | to drive a net::BidirectionalStream. | 
 |  | 
 | Currently Cronet (//components/cronet/ios) is the only consumer of this API, | 
 | but eventually code inside of Chromium should be able to use gRPC by providing | 
 | a net::URLRequestContextGetter. |
