pub struct Memory { /* private fields */ }

A WASM memory.

This type wraps a WebAssembly.Memory from the JavaScript API.

Trait Implementations

impl Clone for Memory

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Memory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl WasmMemory<Engine> for Memory

fn new(_ctx: impl AsContextMut<Engine>, ty: MemoryType) -> Result<Self>

Creates a new linear memory to the store.

fn ty(&self, _ctx: impl AsContext<Engine>) -> MemoryType

Returns the memory type of the linear memory.

fn grow(&self, _ctx: impl AsContextMut<Engine>, additional: u32) -> Result<u32>

Grows the linear memory by the given amount of new pages.

fn current_pages(&self, _ctx: impl AsContext<Engine>) -> u32

Returns the amount of pages in use by the linear memory.

fn read( &self, _ctx: impl AsContext<Engine>, offset: usize, buffer: &mut [u8], ) -> Result<()>

Reads n bytes from memory[offset..offset+n] into buffer where n is the length of buffer.

fn write( &self, _ctx: impl AsContextMut<Engine>, offset: usize, buffer: &[u8], ) -> Result<()>

Writes n bytes to memory[offset..offset+n] from buffer where n if the length of buffer.
