Crate ra_ap_proc_macro_api

Client-side Proc-Macro crate

We separate proc-macro expanding logic to an extern program to allow different implementations (e.g. wasm or dylib loading). And this crate is used to provide basic infrastructure for communication between two processes: Client (RA itself), Server (the external program)

Modules

• msg

• ProcMacro
  A handle to a specific macro (a #[proc_macro] annotated function).
• ProcMacroServer

• RustCInfo
• ServerError

Enums

• ProcMacroKind

Functions

• read_dylib_info
  Read rustc dylib information
• read_version
  Check the version of rustc that was used to compile a proc macro crate’s binary file.
