pub fn into_inner(self) -> (R1, R2)

This is supported on crate features std and chain only.

pub fn get_ref(&self) -> (&R1, &R2)

Trait Implementations

impl<R1: Debug, R2: Debug> Debug for Chain<R1, R2> where
    R1: ReadIntoUninit,
    R2: ReadIntoUninit, 

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

Formats the value using the given formatter.

impl<R1, R2> Read for Chain<R1, R2> where
    R1: ReadIntoUninit,
    R2: ReadIntoUninit, 

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

Read the exact number of bytes required to fill buf.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

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

fn is_read_vectored(&self) -> bool

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

Determines if this Reader has an efficient read_vectored implementation.

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, appending them to 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 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<R1, R2> ReadIntoUninit for Chain<R1, R2> where
    R1: ReadIntoUninit,
    R2: ReadIntoUninit, 

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

This is supported on crate feature std only.

Single attempt to read bytes from Self into buf.

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

This is supported on crate feature std only.

Attempts to fill buf through multiple .read() calls if necessary.

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

This is supported on crate features std and chain only.

Chains / concats two ReadIntoUninit readers into one.
