1.0.0[−][src]Struct tract_hir::internal::tract_downcast_rs::__std::io::Chain
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.
Implementations
impl<T, U> Chain<T, U>
[src]
pub fn into_inner(self) -> (T, U)
1.20.0[src]
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(()) }
pub fn get_ref(&self) -> (&T, &U)
1.20.0[src]
Gets references to the underlying readers in 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(()) }
pub fn get_mut(&mut self) -> (&mut T, &mut U)
1.20.0[src]
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(()) }
