Type Alias Result

Source
pub type Result<T> = Result<T, Error>;
Expand description

A specialized Result type for byteio operations.

This type alias is broadly used across byteio for operations that may produce an error, that is, overflow the underlying buffer.

As with std::io::Result, it is not recommended to import this type directly and shadow core::result::Result, but instead to use byteio::Result to make it easier to distinguish.

§Examples

Trying to decode a string from raw bytes:

use core::str::{self, Utf8Error};

use byteio::WriteBytes;

fn decode_str(buf: &[u8]) -> Result<&str, Utf8Error> {
    str::from_utf8(buf)
}

fn main() -> byteio::Result<()> {
    let mut buf = [0; 5];

    (&mut buf[..]).try_write_exact(b"hello")?;

    match decode_str(&buf) {
        Ok(s) => println!("str from utf8 success!"),
        Err(e) => println!("str from utf8 failure: {}", e),
    }

    Ok(())
}

Aliased Type§

enum Result<T> {
    Ok(T),
    Err(Error),
}

Variants§

Ok(T)

Contains the success value

Err(Error)

Contains the error value
