A linear memory

Required methods

fn size(&self) -> u32

Returns the number of allocated wasm pages.

fn maximum(&self) -> Option<u32>

Returns the maximum number of pages the memory can grow to. Returns None if the memory is unbounded.

fn grow(&mut self, delta: u32) -> Option<u32>

Grow memory by the specified amount of wasm pages.

Returns None if memory can’t be grown by the specified amount of wasm pages.

fn vmmemory(&self) -> VMMemoryDefinition

Return a VMMemoryDefinition for exposing the memory to compiled wasm code.
