A linear memory

Required methods

fn byte_size(&self) -> usize

Returns the number of allocated bytes.

fn maximum_byte_size(&self) -> Option<usize>

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

fn grow_to(&mut self, size: usize) -> Result<()>

Grow memory to the specified amount of bytes.

Returns an error if memory can’t be grown by the specified amount of bytes.

fn vmmemory(&self) -> VMMemoryDefinition

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