std::io::Empty
Struct std::io::Empty
pub struct Empty { /* fields omitted */ }
A reader which is always at EOF.
This struct is generally created by calling empty. Please see the documentation of empty() for more details.
Trait Implementations
impl Read for Empty
[src]
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. Read more
fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>
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>
Read all bytes until EOF in this source, placing them into buf. Read more
fn read_exact(&mut self, buf: &mut [u8]) -> Result<()>1.6.0
Read the exact number of bytes required to fill buf. Read more
fn by_ref(&mut self) -> &mut Self where
Self: Sized,
Self: Sized,
Creates a "by reference" adaptor for this instance of Read. Read more
fn bytes(self) -> Bytes<Self> where
Self: Sized,
Self: Sized,
Transforms this Read instance to an Iterator over its bytes. Read more
fn chars(self) -> Chars<Self> where
Self: Sized,
Self: Sized,
Transforms this Read instance to an Iterator over chars. Read more
fn chain<R: Read>(self, next: R) -> Chain<Self, R> where
Self: Sized,
Self: Sized,
Creates an adaptor which will chain this stream with another. Read more
fn take(self, limit: u64) -> Take<Self> where
Self: Sized,
Self: Sized,
Creates an adaptor which will read at most limit bytes from it. Read more
impl BufRead for Empty
[src]
fn fill_buf(&mut self) -> Result<&[u8]>
Fills the internal buffer of this object, returning the buffer contents. Read more
fn consume(&mut self, _n: usize)
Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to read. Read more
fn read_until(&mut self, byte: u8, buf: &mut Vec<u8>) -> Result<usize>
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>
Read all bytes until a newline (the 0xA byte) is reached, and append them to the provided buffer. Read more
fn split(self, byte: u8) -> Split<Self> where
Self: Sized,
Self: Sized,
Returns an iterator over the contents of this reader split on the byte byte. Read more
fn lines(self) -> Lines<Self> where
Self: Sized,
Self: Sized,
Returns an iterator over the lines of this reader. Read more
impl Debug for Empty
1.16.0
[src]
fn fmt(&self, f: &mut Formatter) -> Result
Formats the value using the given formatter.
