Trait ResultInfallibleExt

Source

pub trait ResultInfallibleExt<T>: Sealed {
    // Required method
    fn unwrap_infallible(self) -> T;
}

Expand description

Extension trait that extracts the value from a Result whose error type is uninhabited.

The signature constrains callers at compile time: the method is only available when the error type is core::convert::Infallible. No panics — the compiler proves the Err arm unreachable from the type.

§Examples

use libdd_common::ResultInfallibleExt;
use std::convert::Infallible;

let result: Result<i32, Infallible> = Ok(42);
assert_eq!(result.unwrap_infallible(), 42);
