Required Methods

fn set_data( &mut self, memory_offset: usize, data_offset: usize, len: usize, data: &[u8], )

fn set(&mut self, memory_offset: usize, data: &[u8])

fn size(&self) -> usize

fn copy(&mut self, destination: usize, source: usize, len: usize)

fn slice(&self, range: Range<usize>) -> impl Deref<Target = [u8]> + '_

Memory slice with range.

Panics

Panics if range is out of scope of allocated memory.

fn resize(&mut self, new_size: usize) -> bool

Resize memory to new size.

Note

It checks memory limits.

Provided Methods

fn slice_len(&self, offset: usize, len: usize) -> impl Deref<Target = [u8]> + '_

Memory slice len

Uses MemoryTrait::slice internally.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
