Crate roam_macros_core 

Code generation core for roam RPC service macros.

This crate contains all the code generation logic for the #[service] proc macro, extracted into a regular library so it can be unit-tested with insta snapshots.

Traits

ToTokens

unsynn defines its own ToTokens trait to be able to implement it for std container types. This is similar to the ToTokens from the quote crate but adds some extra methods and is implemented for more types. Moreover the to_token_iter() method is the main entry point for crating an iterator that can be used for parsing.

Functions

generate_service

Generate all service code for a parsed trait.

method_ok_and_err_types

Extract Ok and Err types from a return type. Returns (ok_type, Some(err_type)) for Result<T, E>, or (type, None) otherwise.

parse

Parse a trait definition from a token stream, returning a codegen-friendly error.

parse_trait

Parse a trait definition from a token stream.

roam_crate

Returns the token stream for accessing the roam crate.
