Struct winter_utils::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]) -> Self

Creates a new slice reader from the specified slice.

Trait Implementations

impl<'a> ByteReader for SliceReader<'a>

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 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<D>( &mut self, num_elements: usize ) -> Result<Vec<D>, DeserializationError>

where Self: Sized, D: Deserializable,

Reads a sequence of bytes from self, attempts to deserialize these bytes into a vector with the specified number of D elements, and returns the result.
