Struct DataMut 

pub struct DataMut<'lt, Layout = Bytes> { /* private fields */ }

A mutable buffer with layout, not aligned to any particular boundary.

Implementations

impl<'lt> DataMut<'lt, Bytes>

pub fn new(data: &'lt mut [u8]) -> Self

Treat a whole input buffer as image bytes.

impl<'lt, L> DataMut<'lt, L>

pub fn with_layout_at( data: &'lt mut [u8], layout: L, start: usize, ) -> Option<Self>

where L: Layout,

Construct from an explicit layout.

This wraps an underlying mutable buffer which has image data of the indicated layout from its start byte onwards.

pub fn as_source(&self) -> AsCopySource<'_, RangeEngine<L>>

where L: Clone + Layout,

An adapter reading from the data as one contiguous chunk.

See RangeEngine for more explanations.

pub fn as_target(&mut self) -> AsCopyTarget<'_, RangeEngine<L>>

where L: Clone + Layout,

An adapter writing to this buffer in one contiguous chunk.

See RangeEngine for more explanations.
