Struct glommio::io::ReadResult

pub struct ReadResult { /* fields omitted */ }

ReadResult encapsulates a buffer, returned by read operations like get_buffer_aligned and read_dma

Implementations

impl ReadResult

pub fn read_at(&self, offset: usize, dst: &mut [u8]) -> usize

Copies the contents of this ReadResult into the byte-slice dst.

The copy starts at position offset into the ReadResult and copies as many bytes as possible until either we don't have more bytes to copy or dst doesn't have more space to hold them.

pub fn slice(&self, extra_offset: usize, len: usize) -> Result<ReadResult>

Creates a slice of this ReadResult with the given offset and length.

Returns an std::io::Error with [std::io::ErrorKind] [InvalidInput] if either offset or offset + len would not fit in the original buffer.

pub fn len(&self) -> usize

The length of this buffer

pub fn as_bytes(&self) -> &[u8]

Allows accessing the contents of this buffer as a byte slice

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

Performs copy-assignment from source.

impl Debug for ReadResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result
