Struct io_streams::IntoInnerError [−][src]
pub struct IntoInnerError<W>(_, _);
Expand description
An error returned by BufWriter::into_inner
which combines an error that
happened while writing out the buffer, and the buffered writer object
which may be used to recover from the condition.
Examples
use std::io::BufWriter;
use std::net::TcpStream;
let mut stream = BufWriter::new(TcpStream::connect("127.0.0.1:34254").unwrap());
// do stuff with the stream
// we want to get our `TcpStream` back, so let's try:
let stream = match stream.into_inner() {
Ok(s) => s,
Err(e) => {
// Here, e is an `IntoInnerError`
panic!("An error occurred");
}
};
Implementations
Returns the error which caused the call to BufWriter::into_inner()
to fail.
This error was returned when attempting to write the internal buffer.
Examples
use std::io::BufWriter;
use std::net::TcpStream;
let mut stream = BufWriter::new(TcpStream::connect("127.0.0.1:34254").unwrap());
// do stuff with the stream
// we want to get our `TcpStream` back, so let's try:
let stream = match stream.into_inner() {
Ok(s) => s,
Err(e) => {
// Here, e is an `IntoInnerError`, let's log the inner error.
//
// We'll just 'log' to stdout for this example.
println!("{}", e.error());
panic!("An unexpected error occurred.");
}
};
Returns the buffered writer instance which generated the error.
The returned object can be used for error recovery, such as re-inspecting the buffer.
Examples
use std::io::BufWriter;
use std::net::TcpStream;
let mut stream = BufWriter::new(TcpStream::connect("127.0.0.1:34254").unwrap());
// do stuff with the stream
// we want to get our `TcpStream` back, so let's try:
let stream = match stream.into_inner() {
Ok(s) => s,
Err(e) => {
// Here, e is an `IntoInnerError`, let's re-examine the buffer:
let buffer = e.into_inner();
// do stuff to try to recover
// afterwards, let's just return the stream
buffer.into_inner().unwrap()
}
};
