Struct mycelium_util::io::Chain

pub struct Chain<T, U> { /* private fields */ }

Adaptor to chain together two readers.

This struct is generally created by calling chain on a reader. Please see the documentation of chain for more details.

Implementations

impl<T, U> Chain<T, U>

pub fn into_inner(self) -> (T, U)

Consumes the Chain, returning the wrapped readers.

pub fn get_ref(&self) -> (&T, &U)

Gets references to the underlying readers in this Chain.

pub fn get_mut(&mut self) -> (&mut T, &mut U)

Gets mutable references to the underlying readers in this Chain.

Care should be taken to avoid modifying the internal I/O state of the underlying readers as doing so may corrupt the internal state of this Chain.

Trait Implementations

impl<T: BufRead, U: BufRead> BufRead for Chain<T, U>

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

Returns the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

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.

impl<T: Debug, U: Debug> Debug for Chain<T, U>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Read, U: Read> Read for Chain<T, U>

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

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

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

Read the exact number of bytes required to fill buf.

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

where Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

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

where Self: Sized,

Creates an adaptor which will chain this stream with another.

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

where Self: Sized,

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