Expand description

Runtime support for the wasm-bindgen tool

This crate contains the runtime support necessary for wasm-bindgen the attribute and tool. Crates pull in the #[wasm_bindgen] attribute through this crate and this crate also provides JS bindings through the JsValue interface.

Modules

This is mostly an internal module, no stability guarantees are provided. Use at your own risk.

Traits

A trait for checked and unchecked casting between JS types.

An extension trait for Option<T> and Result<T, E> for unwraping the T value, or throwing a JS error if it is not available.

Functions

Get the count of live externrefs / JsValues in wasm-bindgen’s heap.

Returns a handle to this wasm instance’s WebAssembly.Table which is the indirect function table used by Rust

Interns Rust strings so that it’s much faster to send them to JS.

Returns a handle to this wasm instance’s WebAssembly.Memory
