Crate wasm_bindgen_backend

A common backend for bindgen crates.

This (internal) crate provides functionality common to multiple bindgen dependency crates. There are 4 main things exported from this crate:

1. TryToTokens

   Provides the ability to attempt conversion from an AST struct into a TokenStream

2. Diagnostic

   A struct used to provide diagnostic responses for failures of said tokenization

3. ast

   Abstract Syntax Tree types used to represent a Rust program, with the necessary metadata to generate bindings for it

4. util

   Common utilities for manipulating parsed types from syn

Modules

• ast
  A representation of the Abstract Syntax Tree of a Rust program, with all the added metadata necessary to generate WASM bindings for it.
• util
  Common utility function for manipulating syn types and handling parsed values

Macros

• bail_span
  Immediately fail and return an Err, with the arguments passed to err_span!
• err_span
  Provide a Diagnostic with the given span and message

Structs

• Diagnostic
  A struct representing a diagnostic to emit to the end-user as an error.

Traits

• TryToTokens
  A trait for converting AST structs into Tokens and adding them to a TokenStream, or providing a diagnostic if conversion fails.
