Crate wasm_bindgen_backend[−][src]
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:
-
Provides the ability to attempt conversion from an AST struct into a TokenStream
-
A struct used to provide diagnostic responses for failures of said tokenization
-
Abstract Syntax Tree types used to represent a Rust program, with the necessary metadata to generate bindings for it
-
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
