Struct netio::Collect

pub struct Collect<R> { /* fields omitted */ }

A reader adapter over an iterator of readers

This adapter is a generalization of std::io::Chain.

This struct is generally created by calling collect::<Collect<_>>() on an iterator of readers. Please see the documentation of collect for more details.

Trait Implementations

impl<R: Read> Read for Collect<R>

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

Creates an adaptor which will chain this stream with another.

fn buffer(self) -> BufReader<Self> where
    Self: Sized, 

Creates a buffered reader with default capacity and default strategies

fn repeat(self) -> Repeat<Self> where
    Self: Sized, 

Transforms this reader into a reader that automatically restarts from the beginning after EOF is reached

impl<R: Read> Read for Collect<R>

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.

unsafe fn initializer(&self) -> Initializer

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

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

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

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

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

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

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

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

fn bytes(self) -> Bytes<Self>

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

fn chars(self) -> Chars<Self>

🔬 This is a nightly-only experimental API. (io)

the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an [Iterator] over [char]s.

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

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

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

impl<R: BufRead> BufRead for Collect<R>

fn fill_buf(&mut self) -> Result<&[u8]>

Fills the internal buffer of this object, returning the buffer contents.

fn consume(&mut self, amt: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to read.

fn read_to_end<B: ?Sized>(&mut self, buf: &mut B) -> Result<()> where
    Self: Sized,
    B: Write, 

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

fn skip_to_end(&mut self) -> Result<()>

Skip all bytes until EOF in this source.

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

Read the exact number of bytes required to fill buf.

fn bytes(self) -> Bytes<Self> where
    Self: Sized, 

Transforms this buffered reader into an iterator over its bytes.

fn read_until<W: ?Sized>(&mut self, delim: u8, buf: &mut W) -> Result<()> where
    Self: Sized,
    W: Write, 

Read all bytes into a buffer until a delimiter is reached.

fn skip_until(&mut self, delim: u8) -> Result<()>

Skips all bytes until a delimiter is reached.

fn split(self, byte: u8) -> Split<Self> where
    Self: Sized, 

Returns an iterator over the contents of this reader split on a delimiter.

impl<R: BufRead> BufRead for Collect<R>

fn fill_buf(&mut self) -> Result<&[u8]>

Fills the internal buffer of this object, returning the buffer contents.

fn consume(&mut self, amt: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to read.

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

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

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

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

fn split(self, byte: u8) -> Split<Self>

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

fn lines(self) -> Lines<Self>

Returns an iterator over the lines of this reader.

impl<R> FromIterator<R> for Collect<R>

fn from_iter<II: IntoIterator<Item = R>>(iter: II) -> Self

Creates a value from an iterator.
