IntoInnerError

Struct IntoInnerError 

Source
pub struct IntoInnerError<W> { /* private fields */ }
Expand description

An error returned by calling into_inner on a writer.

Combines an error that happened while flushing the buffer, and the buffered writer object which may be used to recover from the condition.

§Examples

use bitter::{BitWriter, LittleEndianWriter};
use std::io::{Error, ErrorKind};

#[derive(Debug)]
struct FailingWriter;

impl std::io::Write for FailingWriter {
    fn write(&mut self, _buf: &[u8]) -> std::io::Result<usize> {
        Err(Error::new(ErrorKind::Other, "write failed"))
    }
     
    fn flush(&mut self) -> std::io::Result<()> {
        Err(Error::new(ErrorKind::Other, "flush failed"))
    }
}

let failing_writer = FailingWriter;
let mut writer = LittleEndianWriter::new(failing_writer);
writer.write_bit(true).unwrap();

let into_inner_error = writer.into_inner().unwrap_err();

// Access the error that occurred during flushing
let flush_error = into_inner_error.error();
println!("Flush failed: {}", flush_error);

// Recover the original writer for potential retry
let recovered_writer = into_inner_error.into_inner();

Implementations§

Source§

impl<W> IntoInnerError<W>

Source

pub fn error(&self) -> &Error

Returns the error which caused the call to into_inner() to fail.

This error was returned when attempting to flush the internal buffer.

Source

pub fn into_inner(self) -> W

Returns the writer instance which generated the error.
