Trait for implementing Wasm Memory used by Wasmer.

Required methods

pub fn ty(&self) -> &MemoryType[src]

Returns the memory type for this memory.

pub fn style(&self) -> &MemoryStyle[src]

Returns the memory style for this memory.

pub fn size(&self) -> Pages[src]

Returns the number of allocated wasm pages.

pub fn grow(&self, delta: Pages) -> Result<Pages, MemoryError>[src]

Grow memory by the specified amount of wasm pages.

pub fn vmmemory(&self) -> NonNull<VMMemoryDefinition>[src]

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.
