pub struct Chain<T, U> { /* fields omitted */ }
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.
Consumes the Chain
, returning the wrapped readers.

use std::fs::File;
fn main() -> io::Result<()> {
let mut foo_file = File::open("foo.txt")?;

let (foo_file, bar_file) = chain.into_inner();
Ok(())
}
Gets references to the underlying readers in this Chain
.

let mut foo_file = File::open("foo.txt")?;

Ok(())
}
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
.

Returns the contents of the internal buffer, filling it with more data from the inner reader if it is empty. Read more
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
Read all bytes into buf
until the delimiter byte
or EOF is reached. Read more
Read all bytes until a newline (the 0xA byte) is reached, and append them to the provided buffer. Read more
Returns an iterator over the contents of this reader split on the byte byte
. Read more
Returns an iterator over the lines of this reader. Read more
Pull some bytes from this source into the specified buffer, returning how many bytes were read. Read more
🔬 This is a nightly-only experimental API. (read_initializer
)
Determines if this Read
er can work with buffers of uninitialized memory. Read more
Read all bytes until EOF in this source, placing them into buf
. Read more
Read all bytes until EOF in this source, appending them to buf
. Read more
Read the exact number of bytes required to fill buf
. Read more
Creates a "by reference" adaptor for this instance of Read
. Read more
Transforms this Read
instance to an [Iterator
] over its bytes. Read more
Creates an adaptor which will chain this stream with another. Read more
Creates an adaptor which will read at most limit
bytes from it. Read more
Formats the value using the given formatter. Read more
