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.

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

fn peek_u8(&mut self) -> Option<u8>

Returns the next byte without consuming it.

fn read_u8(&mut self) -> Result<u8, DecodeError>

Read a single byte from the reader.

fn read_u16(&mut self) -> Result<u16, DecodeError>

Read a u16 from the reader.

fn read_u32(&mut self) -> Result<u32, DecodeError>

Read a u32 from the reader.

fn read_u64(&mut self) -> Result<u64, DecodeError>

Read a u64 from the reader.

fn read_u128(&mut self) -> Result<u128, DecodeError>

Read a u128 from the reader.
