Trait Implementations

impl Read for Empty[src]

fn read_vectored(&mut self, bufs: &mut [IoSliceMut]) -> Result<usize>1.36.0[src]

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

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

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

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

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

fn read_exact(&mut self, buf: &mut [u8]) -> Result<()>1.6.0[src]

Read the exact number of bytes required to fill buf. Read more

Important traits for &'_ mut F
fn by_ref(&mut self) -> &mut Self where
    Self: Sized
[src]

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

Important traits for Bytes<R>
fn bytes(self) -> Bytes<Self> where
    Self: Sized
[src]

Transforms this Read instance to an [Iterator] over its bytes. Read more

Important traits for Chain<T, U>
fn chain<R: Read>(self, next: R) -> Chain<Self, R> where
    Self: Sized
[src]

Creates an adaptor which will chain this stream with another. Read more

Important traits for Take<T>
fn take(self, limit: u64) -> Take<Self> where
    Self: Sized
[src]

Creates an adaptor which will read at most limit bytes from it. Read more

impl BufRead for Empty[src]

fn read_until(&mut self, byte: u8, buf: &mut Vec<u8>) -> Result<usize>[src]

Read all bytes into buf until the delimiter byte or EOF is reached. Read more

fn read_line(&mut self, buf: &mut String) -> Result<usize>[src]

Read all bytes until a newline (the 0xA byte) is reached, and append them to the provided buffer. Read more

Important traits for Split<B>
fn split(self, byte: u8) -> Split<Self> where
    Self: Sized
[src]

Returns an iterator over the contents of this reader split on the byte byte. Read more

Important traits for Lines<B>
fn lines(self) -> Lines<Self> where
    Self: Sized
[src]

Returns an iterator over the lines of this reader. Read more
