//! When generating our web_sys APIs we default to setting slice references that
|
|
//! get passed to JS as mutable in case they get mutated in JS.
|
|
//!
|
|
//! In certain cases we know for sure that the slice will not get mutated - for
|
|
//! example when working with the WebGlRenderingContext APIs.
|
|
//!
|
|
//! These tests ensure that whitelisted methods do indeed accept mutable slices.
|
|
//!
|
|
//! @see https://github.com/rustwasm/wasm-bindgen/issues/1005
