Struct thrift::transport::TBufferedReadTransport

pub struct TBufferedReadTransport<C>
where
    C: Read,
{ /* private fields */ }

Transport that reads messages via an internal buffer.

A TBufferedReadTransport maintains a fixed-size internal read buffer. On a call to TBufferedReadTransport::read(...) one full message - both fixed-length header and bytes - is read from the wrapped channel and buffered. Subsequent read calls are serviced from the internal buffer until it is exhausted, at which point the next full message is read from the wrapped channel.

Examples

Create and use a TBufferedReadTransport.

use std::io::Read;
use thrift::transport::{TBufferedReadTransport, TTcpChannel};

let mut c = TTcpChannel::new();
c.open("localhost:9090").unwrap();

let mut t = TBufferedReadTransport::new(c);

t.read(&mut vec![0u8; 1]).unwrap();

Implementations

impl<C> TBufferedReadTransport<C>

where C: Read,

pub fn new(channel: C) -> TBufferedReadTransport<C>

Create a TBufferedTransport with default-sized internal read and write buffers that wraps the given TIoChannel.

pub fn with_capacity( read_capacity: usize, channel: C, ) -> TBufferedReadTransport<C>

Create a TBufferedTransport with an internal read buffer of size read_capacity and an internal write buffer of size write_capacity that wraps the given TIoChannel.

Trait Implementations

impl<C> Debug for TBufferedReadTransport<C>

where C: Read + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<C> Read for TBufferedReadTransport<C>

where C: Read,

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

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

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_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Reads the exact number of bytes required to fill 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.
