Trait ResultErrorExt

pub trait ResultErrorExt<T>: Sealed {
    // Required method
    fn unexpect(self) -> Result<T, RawUnexpected>;
}

Provides Result::unexpect

Required Methods

fn unexpect(self) -> Result<T, RawUnexpected>

Converts Result<T, E> to Result<T, RawUnexpected>.

Examples

use exun::*;
use core::fmt::Error;

let res: Result<i32, Error> = Err(Error);
let res: Result<i32, RawUnexpected> = res.unexpect();

Use with the try operator

use exun::*;
use core::fmt::Error;

fn foo() -> Result<i32, UnexpectedError> {
    let res: Result<i32, Error> = Err(Error);
    Ok(res.unexpect()?)
}

Use with the try operator and Exun

use exun::*;
use core::fmt::Error;

fn foo() -> Result<i32, Exun<(), UnexpectedError>> {
    let res: Result<i32, Error> = Err(Error);
    Ok(res.unexpect()?)
}
