Returns the error which caused the call to 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()
    }
};
