Expand description

Trait for the backing storage of a raw bitmap.

Provided Associated Constants§

Source

const SUPPORTS_GROW: bool = false

True if this storage supports growing.

Required Methods§

Source

fn allocate(&mut self, size: usize) -> Result<(), Status>

Allocates at least size bytes of storage.

Source

fn get_data(&self) -> &[usize]

Returns a read-only slice of usize words to the underlying storage.

Source

fn get_data_mut(&mut self) -> &mut [usize]

Returns a mutable slice of usize words to the underlying storage.

Provided Methods§

Source

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

Optionally grows the storage to at least size bytes.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
