Struct genio::std_impls::GenioWrite

pub struct GenioWrite<W>(_);

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

Methods

impl<W: Write> GenioWrite<W>

pub fn new(writer: W) -> Self

Wraps std writer into genio writer.

pub fn into_inner(self) -> W

Unwraps std writer into genio writer.

Trait Implementations

impl<W: Write> Write for GenioWrite<W>

type WriteError = Error

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

type FlushError = Error

Value of this type is returned when flush() fails. In case of low-level writers flush often does nothing and therefore doesn't return error, so this type might be Void.

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

Write a buffer into this object, returning how many bytes were written.

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

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn size_hint(&mut self, _bytes: usize)

Hints the writer how much bytes will be written after call to this function. If the maximum amount of bytes to be written is known then it should be passed as argument. If the maximum amount is unknown, then minimum should be passed.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::WriteError>

Attempts to write an entire buffer into this Write.

fn uses_size_hint(&self) -> bool

Reports to the caller whether size hint is actually used. This can prevent costly computation of size hint that would be thrown away.
