Struct BufferReader

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

StreamingReader backend for a byte slice

Implementations

impl<'a> BufferReader<'a>

pub fn new(buffer: &'a [u8]) -> BufferReader<'a>

Make a new BufferReader around a byte slice

pub fn cursor(&self) -> usize

How many bytes have been read thus far

Trait Implementations

impl<'a> From<&'a [u8]> for BufferReader<'a>

fn from(buffer: &'a [u8]) -> Self

Converts to this type from the input type.

impl<'a> StreamingReader for BufferReader<'a>

type Error = BufferReaderError

The kind of Error the implementation produces

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

Read bytes from the underlying data source into the provided buf. Should return an error if insufficient bytes are available to fully fill buf.

fn share_bytes(&mut self, len: usize) -> Result<&[u8], Self::Error>

Expose an aliased view of a subset of the underlying data as immutable bytes.
