Struct `Chain`

struct Chain<T, U> { ... }

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.

Implementations

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

fn into_inner(self: Self) -> (T, U)

Consumes the Chain, returning the wrapped readers.

Examples

use std::io;
use std::io::prelude::*;
use std::fs::File;

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

    let chain = foo_file.chain(bar_file);
    let (foo_file, bar_file) = chain.into_inner();
    Ok(())
}

fn get_ref(self: &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.

Examples

use std::io;
use std::io::prelude::*;
use std::fs::File;

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

    let chain = foo_file.chain(bar_file);
    let (foo_file, bar_file) = chain.get_ref();
    Ok(())
}

fn get_mut(self: &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.

Examples

use std::io;
use std::io::prelude::*;
use std::fs::File;

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

    let mut chain = foo_file.chain(bar_file);
    let (foo_file, bar_file) = chain.get_mut();
    Ok(())
}
