Struct SliceReader 

pub struct SliceReader<'storage> { /* private fields */ }

A reader type for &[u8] slices. Implements both [Reader] and [BorrowReader], and thus can be used for borrowed data.

Implementations

impl<'storage> SliceReader<'storage>

pub const fn new(bytes: &'storage [u8]) -> Self

Constructs a slice reader

Trait Implementations

impl<'storage> BorrowReader<'storage> for SliceReader<'storage>

fn take_bytes(&mut self, length: usize) -> Result<&'storage [u8], DecodeError>

Read exactly length bytes and return a slice to this data. If not enough bytes could be read, an error should be returned.

impl<'storage> Reader for SliceReader<'storage>

fn read(&mut self, bytes: &mut [u8]) -> Result<(), DecodeError>

Fill the given bytes argument with values. Exactly the length of the given slice must be filled, or else an error must be returned. Fill the given bytes argument with values. Exactly the length of the given slice must be filled, or else an error must be returned.

fn peek_read(&mut self, n: usize) -> Option<&'storage [u8]>

If this reader wraps a buffer of any kind, this function lets callers access contents of the buffer without passing data through a buffer first.

fn consume(&mut self, n: usize)

If an implementation of peek_read is provided, an implementation of this function must be provided so that subsequent reads or peek-reads do not return the same bytes
