[−][src]Trait wasmer_vm::Memory
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.
