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.

Implementations on Foreign Types

impl Memory for LinearMemory

pub fn ty(&self) -> MemoryType

Returns the type for this memory.

pub fn style(&self) -> &MemoryStyle

Returns the memory style for this memory.

pub fn size(&self) -> Pages

Returns the number of allocated wasm pages.

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

Grow memory by the specified amount of wasm pages.

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

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

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