Struct bincode::de::read::IoReader

pub struct IoReader<R> {
    reader: R,
    temp_buffer: Vec<u8>,
}

A BincodeRead implementation for io::Readers

Fields

reader: R

temp_buffer: Vec<u8>

Implementations

impl<R> IoReader<R>

pub(crate) fn new(r: R) -> IoReader<R>

Constructs an IoReadReader

impl<R> IoReader<R>

where R: Read,

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

Trait Implementations

impl<'a, R> BincodeRead<'a> for IoReader<R>

where R: Read,

fn forward_read_str<V>(&mut self, length: usize, visitor: V) -> Result<V::Value>

where V: Visitor<'a>,

Check that the next length bytes are a valid string and pass it on to the serde reader.

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

Transfer ownership of the next length bytes to the caller.

fn forward_read_bytes<V>( &mut self, length: usize, visitor: V, ) -> Result<V::Value>

where V: Visitor<'a>,

Pass a slice of the next length bytes on to the serde reader.

impl<R: Read> Read for IoReader<R>

fn read(&mut self, out: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_exact(&mut self, out: &mut [u8]) -> Result<()>

Reads the exact number of bytes required to fill buf.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

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

Reads all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Reads all bytes until EOF in this source, appending them to buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Reads the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.
