Tracking Issue for producing a `Result<(), E>` from a `bool`

[LimpSquid]

Feature gate: #![feature(bool_to_result)]

This is a tracking issue for adding bool::ok_or and bool::ok_or_else as discussed in rust-lang/libs-team#606

This feature allows you to directly produce a Result<(), E> from a bool and is a short-hand for .then_some(()).ok_or(...) or .then_some(()).ok_or_else(|| ...).

Public API

assert_eq!(false.ok_or(0), Err(0));
assert_eq!(true.ok_or(0), Ok(()));

assert_eq!(false.ok_or_else(|| 0), Err(0));
assert_eq!(true.ok_or_else(|| 0), Ok(()));
