Struct MutSliceRead

pub struct MutSliceRead<'a> { /* private fields */ }

A CBOR input source that reads from a slice of bytes, and can move data around internally to reassemble indefinite strings without the need of an allocated scratch buffer.

Implementations

impl<'a> MutSliceRead<'a>

pub fn new(slice: &'a mut [u8]) -> MutSliceRead<'a>

Creates a CBOR input source to read from a slice of bytes.

Trait Implementations

impl<'a> Debug for MutSliceRead<'a>

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

Formats the value using the given formatter.

impl<'a> Read<'a> for MutSliceRead<'a>

fn next(&mut self) -> Result<Option<u8>>

Read the next byte from the input, if any.

fn peek(&mut self) -> Result<Option<u8>>

Peek at the next byte of the input, if any. This does not advance the reader, so the result of this function will remain the same until a read or clear occurs.

fn clear_buffer(&mut self)

Clear the underlying scratch buffer

fn read_to_buffer(&mut self, n: usize) -> Result<()>

Append n bytes from the reader to the reader’s scratch buffer (without clearing it)

fn take_buffer<'b>(&'b mut self) -> EitherLifetime<'b, 'a>

Read out everything accumulated in the reader’s scratch buffer. This may, as a side effect, clear it.

fn read_into(&mut self, buf: &mut [u8]) -> Result<()>

Read from the input until buf is full or end of input is encountered.

fn discard(&mut self)

Discard any data read by peek.

fn offset(&self) -> u64

Returns the offset from the start of the reader.

fn read<'a>(&'a mut self, n: usize) -> Result<EitherLifetime<'a, 'de>>

Read n bytes from the input.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
