Methods from Deref<Target = Uint8Array>

pub fn copy_to(&self, dst: &mut [u8])

Copy the contents of this JS typed array into the destination Rust slice.

This function will efficiently copy the memory from a typed array into this wasm module's own linear memory, initializing the memory destination provided.

Panics

This function will panic if this typed array's length is different than the length of the provided dst array.

pub fn to_vec(&self) -> Vec<u8>

Efficiently copies the contents of this JS typed array into a new Vec.

pub fn fill(&self, value: u8, start: u32, end: u32) -> Uint8Array

The fill() method fills all the elements of an array from a start index to an end index with a static value. The end index is not included.

MDN documentation

pub fn buffer(&self) -> ArrayBuffer

The buffer accessor property represents the ArrayBuffer referenced by a TypedArray at construction time.

pub fn subarray(&self, begin: u32, end: u32) -> Uint8Array

The subarray() method stores multiple values in the typed array, reading input values from a specified array.

pub fn slice(&self, begin: u32, end: u32) -> Uint8Array

The slice() method returns a shallow copy of a portion of a typed array into a new typed array object. This method has the same algorithm as Array.prototype.slice().

pub fn for_each(&self, callback: &mut dyn FnMut(u8, u32, Uint8Array))

The forEach() method executes a provided function once per array element. This method has the same algorithm as Array.prototype.forEach(). TypedArray is one of the typed array types here.

pub fn length(&self) -> u32

The length accessor property represents the length (in elements) of a typed array.

pub fn byte_length(&self) -> u32

The byteLength accessor property represents the length (in bytes) of a typed array.

pub fn byte_offset(&self) -> u32

The byteOffset accessor property represents the offset (in bytes) of a typed array from the start of its ArrayBuffer.

pub fn set(&self, src: &JsValue, offset: u32)

The set() method stores multiple values in the typed array, reading input values from a specified array.
