Struct RestrictedMemory 

pub struct RestrictedMemory<M: Memory> { /* private fields */ }

RestrictedMemory creates a limited view of another memory. This allows one to divide the main memory into non-intersecting ranges and use different layouts in each region.

Implementations

impl<M: Memory> RestrictedMemory<M>

pub fn new(memory: M, page_range: Range<u64>) -> Self

Trait Implementations

impl<M: Clone + Memory> Clone for RestrictedMemory<M>

fn clone(&self) -> RestrictedMemory<M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Memory> Memory for RestrictedMemory<M>

fn size(&self) -> u64

Returns the current size of the memory in WebAssembly pages.

fn grow(&self, delta: u64) -> i64

Grows the memory by pages pages filled with zeroes.

fn read(&self, offset: u64, dst: &mut [u8])

Copies dst.len() bytes from memory starting at offset into dst.

unsafe fn read_unsafe(&self, offset: u64, dst: *mut u8, count: usize)

Unsafe variant of read for advanced use.

fn write(&self, offset: u64, src: &[u8])

Copies src.len() bytes from src into memory starting at offset.
