# Struct std::io::IntoInnerError 1.0.0[−][src]

    pub struct IntoInnerError<W>(_, _);

An error returned by `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");
        }
    };Run

## Methods

###

`impl<W> IntoInnerError<W>`

[src]

####

`pub fn error(&self) -> &Error`

[src]

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.");
        }
    };Run

####

`pub fn into_inner(self) -> W`

[src]

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()
        }
    };Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
