Struct Chain 

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

Adapter 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.

See std::io::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.

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.

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, via Read methods, if empty.

fn consume(&mut self, amt: usize)

Marks the given amount of additional bytes from the internal buffer as having been read. Subsequent calls to read only return bytes that have not been marked as read.

fn has_data_left(&mut self) -> Result<bool>

Checks if there is any data left to be read.

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

Skips all bytes until the delimiter byte or EOF is reached.

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: IoBuf, U: IoBuf> IoBuf for Chain<T, U>

fn remaining(&self) -> usize

Returns the number of bytes between the current position and the end of the buffer.

fn is_empty(&self) -> bool

Returns true if there are no remaining bytes in the buffer.

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.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<()>

Pull some bytes from this source into the specified buffer.

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

Read the exact number of bytes required to fill buf.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<()>

Reads the exact number of bytes required to fill cursor.

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

where Self: Sized,

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

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

where Self: Sized,

Creates an adapter which will chain this stream with another.

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

where Self: Sized,

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