Struct grin_core::ser::BufReader

pub struct BufReader<'a, B: Buf> { /* private fields */ }

Protocol version-aware wrapper around a Buf impl

Implementations

impl<'a, B: Buf> BufReader<'a, B>

pub fn new(buf: &'a mut B, version: ProtocolVersion) -> Self

Construct a new BufReader

pub fn bytes_read(&self) -> u64

The total bytes read

pub fn body<T: Readable>(&mut self) -> Result<T, Error>

Convenience function to read from the buffer and deserialize

Trait Implementations

impl<'a, B: Buf> Reader for BufReader<'a, B>

fn deserialization_mode(&self) -> DeserializationMode

The mode this reader is reading from

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, len: 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.

fn read_empty_bytes(&mut self, length: usize) -> Result<(), Error>

Read a fixed number of “empty” bytes from the underlying reader. It is an error if any non-empty bytes encountered.
