Trait Implementations

impl Clone for SharedMemory

fn clone(&self) -> SharedMemory

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl RuntimeLinearMemory for SharedMemory

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( &mut self, _delta_pages: u64, _store: Option<&mut dyn Store> ) -> Result<Option<(usize, usize)>>

Grows a memory by delta_pages.

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

Grow memory to the specified amount of bytes.

fn vmmemory(&mut self) -> VMMemoryDefinition

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

fn needs_init(&self) -> bool

Does this memory need initialization? It may not if it already has initial contents courtesy of the MemoryImage passed to RuntimeMemoryCreator::new_memory().

fn as_any_mut(&mut self) -> &mut dyn Any

Used for optional dynamic downcasting.

fn wasm_accessible(&self) -> Range<usize>

Returns the range of addresses that may be reached by WebAssembly.
