Trait for implementing Wasm Memory used by Wasmer.

Required methods

fn ty(&self) -> &MemoryType

Returns the memory type for this memory.

fn style(&self) -> &MemoryStyle

Returns the memory style for this memory.

fn size(&self) -> Pages

Returns the number of allocated wasm pages.

fn grow(&self, delta: Pages) -> Result<Pages, MemoryError>

Grow memory by the specified amount of wasm pages.

fn vmmemory(&self) -> NonNull<VMMemoryDefinition>

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

The pointer returned in VMMemoryDefinition must be valid for the lifetime of this memory.
