Struct SliceReader 

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

Implements ByteReader trait for a slice of bytes.

NOTE: If you are building with the std feature, you should probably prefer std::io::Cursor instead. However, SliceReader is still useful in no-std environments until stabilization of the core_io_borrowed_buf feature.

Implementations

impl<'a> SliceReader<'a>

pub fn new(source: &'a [u8]) -> SliceReader<'a>

Creates a new slice reader from the specified slice.

Trait Implementations

impl ByteReader for SliceReader<'_>

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

Returns a single byte read from self.

fn peek_u8(&self) -> Result<u8, DeserializationError>

Returns the next byte to be read from self without advancing the reader to the next byte.

fn read_slice(&mut self, len: usize) -> Result<&[u8], DeserializationError>

Returns a slice of bytes of the specified length read from self.

fn read_array<const N: usize>( &mut self, ) -> Result<[u8; N], DeserializationError>

Returns a byte array of length N read from self.

fn check_eor(&self, num_bytes: usize) -> Result<(), DeserializationError>

Checks if it is possible to read at least num_bytes bytes from this ByteReader

fn has_more_bytes(&self) -> bool

Returns true if there are more bytes left to be read from self.

fn max_alloc(&self, _element_size: usize) -> usize

Returns the maximum number of elements that can be safely allocated, given each element occupies element_size bytes when serialized.

fn read_bool(&mut self) -> Result<bool, DeserializationError>

Returns a boolean value read from self consuming 1 byte from the reader.

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

Returns a u16 value read from self in little-endian byte order.

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

Returns a u32 value read from self in little-endian byte order.

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

Returns a u64 value read from self in little-endian byte order.

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

Returns a u128 value read from self in little-endian byte order.

fn read_usize(&mut self) -> Result<usize, DeserializationError>

Returns a usize value read from self in vint64 format.

fn read_vec(&mut self, len: usize) -> Result<Vec<u8>, DeserializationError>

Returns a byte vector of the specified length read from self.

fn read_string( &mut self, num_bytes: usize, ) -> Result<String, DeserializationError>

Returns a String of the specified length read from self.

fn read<D>(&mut self) -> Result<D, DeserializationError>

where Self: Sized, D: Deserializable,

Reads a deserializable value from self.

fn read_many_iter<D>( &mut self, num_elements: usize, ) -> Result<ReadManyIter<'_, Self, D>, DeserializationError>

where Self: Sized, D: Deserializable,

Returns an iterator that deserializes num_elements instances of D from this reader.
