syn-mid

Build Status version documentation license Rustc Version

Providing the features between “full” and “derive” of syn.

This crate provides the following two unique data structures.

  • syn_mid::ItemFn -- A function whose body is not parsed.

    fn process(n: usize) -> Result<()> { ... }
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^     ^
    
  • syn_mid::Block -- A block whose body is not parsed.

    { ... }
    ^     ^
    

Other data structures are the same as data structures of syn. Also, if the “full” feature is enabled, those items are reexported from syn.

Note that if you use syn with “full” feature and use syn-mid without “full” feature at the same time, errors due to type mismatch may occur.

Usage

Add this to your Cargo.toml:

[dependencies]
syn-mid = "0.1"

The current version of syn-mid requires Rust 1.15 or later.

Optional features

syn-mid in the default features aims to provide the features between “full” and “derive” of syn.

  • derive (enabled by default) — Data structures for representing the possible input to a custom derive, including structs and enums and types.
  • full — Data structures for representing the syntax tree of all valid Rust source code, including items and expressions.
  • clone-impls (enabled by default) — Clone impls for all syntax tree types.
  • extra-traits — Debug, Eq, PartialEq, Hash impls for all syntax tree types.

Note that if both “derive” and “full” features are disabled, a compile error occurs.
