Struct genio::std_impls::GenioRead

pub struct GenioRead<R>(_);

Wrapper providing genio::Read trait for std::io::Read types.

Methods

impl<R: Read> GenioRead<R>

pub fn new(reader: R) -> Self

Wraps std readerinto genio reader.

pub fn into_inner(self) -> R

Unwraps std reader genio reader.

Trait Implementations

impl<R: Read> Read for GenioRead<R>

type ReadError = Error

Value of this type is returned when read() fails.

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

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

fn read_exact(
    &mut self,
    buf: &mut [u8]
) -> Result<(), ReadExactError<Self::ReadError>>

Read the exact number of bytes required to fill buf.

fn available_bytes(&self, _at_least: usize) -> bool

Hints whether there are at least at_least bytes available.

fn chain<R: Read>(self, other: R) -> Chain<Self, R> where
    Self: Sized, 

Chains another reader after self. When self ends (returns Ok(0)), the other reader will provide bytes to read.

fn read_to_end<T: ExtendFromReader>(
    &mut self,
    container: &mut T
) -> Result<usize, ExtendError<Self::ReadError, T::ExtendError>> where
    Self: ReadOverwrite, 

Reads all bytes into any type that can be extended by a reader. This is more generic than the case of std::io and might enable some optimizations.

fn by_ref(&mut self) -> &mut Self where
    Self: Sized, 

Creates a "by reference" adaptor for this instance of Read.
