Memory context is used by Wasmer Environment for read-write access to WASM linear memory.

Required Methods

fn get_memory(&self) -> &Memory

fn get_alloc(&self) -> &NativeFunc<u32, WasmPtr<u8, Array>>

Provided Methods

fn write_bytes_to_memory(&self, value: Vec<u8>, val_ptr_ptr: u32) -> Result<u32>

set the return values to memory and return the length

fn read_bytes_from_memory(&self, offset: u32, len: u32) -> Result<Vec<u8>>

read bytes from memory given the offset and len of the memory location
