Implementations defined how different numbers and binary structures are read from an underlying stream or container (depending on implementation).

Required methods

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

Read a u8 from the underlying Read

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

Read a u16 from the underlying Read

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

Read a u32 from the underlying Read

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

Read a u64 from the underlying Read

fn read_i32(&mut self) -> Result<i32, Error>

Read a i32 from the underlying Read

fn read_i64(&mut self) -> Result<i64, Error>

Read a i64 from the underlying Read

fn read_bytes_len_prefix(&mut self) -> Result<Vec<u8>, Error>

Read a u64 len prefix followed by that number of exact bytes.

fn read_fixed_bytes(&mut self, length: usize) -> Result<Vec<u8>, Error>

Read a fixed number of bytes from the underlying reader.

fn expect_u8(&mut self, val: u8) -> Result<u8, Error>

Consumes a byte from the reader, producing an error if it doesn't have the expected value

fn protocol_version(&self) -> ProtocolVersion

Access to underlying protocol version to support version specific deserialization logic.

Implementors

impl<'a> Reader for BinReader<'a>[src]

Utility wrapper for an underlying byte Reader. Defines higher level methods to read numbers, byte vectors, hashes, etc.

fn read_bytes_len_prefix(&mut self) -> Result<Vec<u8>, Error>[src]

Read a variable size vector from the underlying Read. Expects a usize

fn read_fixed_bytes(&mut self, len: usize) -> Result<Vec<u8>, Error>[src]

Read a fixed number of bytes.

impl<'a> Reader for StreamingReader<'a>[src]

Note: We use read_fixed_bytes() here to ensure our "async" I/O behaves as expected.

fn read_bytes_len_prefix(&mut self) -> Result<Vec<u8>, Error>[src]

Read a variable size vector from the underlying stream. Expects a usize

fn read_fixed_bytes(&mut self, len: usize) -> Result<Vec<u8>, Error>[src]

Read a fixed number of bytes.
