Struct wasm_bindgen::Clamped

pub struct Clamped<T>(pub T);

Expand description

A wrapper type around slices and vectors for binding the Uint8ClampedArray array in JS.

If you need to invoke a JS API which must take Uint8ClampedArray array, then you can define it as taking one of these types:

Clamped<&[u8]>
Clamped<&mut [u8]>
Clamped<Vec<u8>>

All of these types will show up as Uint8ClampedArray in JS and will have different forms of ownership in Rust.
