Struct parity_wasm::interpreter::MemoryInstance

pub struct MemoryInstance { /* fields omitted */ }

Linear memory instance.

Methods

impl MemoryInstance

fn new(memory_type: &MemoryType) -> Result<Arc<Self>, Error>

Create new linear memory instance.

fn size(&self) -> u32

Return linear memory size (in pages).

fn get(&self, offset: u32, size: usize) -> Result<Vec<u8>, Error>

Get data at given offset.

fn set(&self, offset: u32, value: &[u8]) -> Result<(), Error>

Set data at given offset.

fn grow(&self, pages: u32) -> Result<u32, Error>

Increases the size of the linear memory by given number of pages. Returns -1 if allocation fails or previous memory size, if succeeds.
