Struct wasm_runtime_layer::Memory

pub struct Memory { /* private fields */ }

A Wasm linear memory reference.

Implementations

impl Memory

pub fn new<C: AsContextMut>(ctx: C, ty: MemoryType) -> Result<Self>

Creates a new linear memory to the store.

pub fn ty<C: AsContext>(&self, ctx: C) -> MemoryType

Returns the memory type of the linear memory.

pub fn grow<C: AsContextMut>(&self, ctx: C, additional: u32) -> Result<u32>

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

pub fn current_pages<C: AsContext>(&self, ctx: C) -> u32

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

pub fn read<C: AsContext>( &self, ctx: C, offset: usize, buffer: &mut [u8] ) -> Result<()>

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

pub fn write<C: AsContextMut>( &self, ctx: C, offset: usize, buffer: &[u8] ) -> Result<()>

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