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.
impl<T, U> Chain<T, U>[src]
pub fn into_inner(self) -> (T, U)[src]1.20.0
Consumes the Chain, returning the wrapped readers.
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(())
}pub fn get_ref(&self) -> (&T, &U)[src]1.20.0
Gets references to the underlying readers in this Chain.
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(())
}pub fn get_mut(&mut self) -> (&mut T, &mut U)[src]1.20.0
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.

use std::fs::File;

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(())
