pub unsafe fn view(rust: &[i8]) -> Int8Array

Creates a JS typed array which is a view into wasm’s linear memory at the slice specified.

This function returns a new typed array which is a view into wasm’s memory. This view does not copy the underlying data.

Safety

Views into WebAssembly memory are only valid so long as the backing buffer isn’t resized in JS. Once this function is called any future calls to Box::new (or malloc of any form) may cause the returned value here to be invalidated. Use with caution!

Additionally the returned object can be safely mutated but the input slice isn’t guaranteed to be mutable.

Finally, the returned object is disconnected from the input slice’s lifetime, so there’s no guarantee that the data is read at the right time.

pub unsafe fn view_mut_raw(ptr: *mut i8, length: usize) -> Int8Array

Creates a JS typed array which is a view into wasm’s linear memory at the specified pointer with specified length.

This function returns a new typed array which is a view into wasm’s memory. This view does not copy the underlying data.

Safety

Views into WebAssembly memory are only valid so long as the backing buffer isn’t resized in JS. Once this function is called any future calls to Box::new (or malloc of any form) may cause the returned value here to be invalidated. Use with caution!

Additionally the returned object can be safely mutated, the changes are guaranteed to be reflected in the input array.

pub unsafe fn raw_copy_to_ptr(&self, dst: *mut i8)

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

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

Safety

This function requires dst to point to a buffer large enough to fit this array’s contents.

pub fn copy_to(&self, dst: &mut [i8])

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 copy_to_uninit<'dst>( &self, dst: &'dst mut [MaybeUninit<i8>], ) -> &'dst mut [i8]

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 copy_from(&self, src: &[i8])

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

This function will efficiently copy the memory from within the Wasm module’s own linear memory to this typed array.

Panics

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

pub fn to_vec(&self) -> Vec<i8>

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