[Merged by Bors] - Replace the `bool` argument of `Timer` with `TimerMode` #6247

lovelymono · 2022-10-13T11:06:16Z

As mentioned in #2926, it's better to have an explicit type that clearly communicates the intent of the timer mode rather than an opaque boolean, which can be only understood when knowing the signature or having to look up the documentation.

This also opens up a way to merge different timers, such as Stopwatch, and possibly future ones, such as DiscreteStopwatch and DiscreteTimer from #2683, into one struct.

Signed-off-by: Lena Milizé me@lvmn.org

Objective

Fixes #2926.

Solution

Introduce TimerMode which replaces the bool argument of Timer constructors. A Default value for TimerMode is Once.

Changelog

Added

TimerMode enum, along with variants TimerMode::Once and TimerMode::Repeating

Changed

Replace bool argument of Timer::new and Timer::from_seconds with TimerMode
Change repeating: bool field of Timer with mode: TimerMode

Migration Guide

Replace Timer::new(duration, false) with Timer::new(duration, TimerMode::Once).
Replace Timer::new(duration, true) with Timer::new(duration, TimerMode::Repeating).
Replace Timer::from_seconds(seconds, false) with Timer::from_seconds(seconds, TimerMode::Once).
Replace Timer::from_seconds(seconds, true) with Timer::from_seconds(seconds, TimerMode::Repeating).
Change timer.repeating() to timer.mode() == TimerMode::Repeating.

As mentioned in #2926, it's better to have an explicit type that clearly communicates the intent of the timer mode rather than an opaque boolean, which can be only understood when knowing the signature or reading the documentation. Signed-off-by: Lena Milizé <me@lvmn.org>

IMHO, I think all usage of bool for repeating should be completly replaced by TimerMode to avoid mixing and confusion.

Replaces Timer::set_repeating and Timer::repeating with Timer::set_mode and Timer::mode, respectively. Adds PartialEq, Eq, Hash to TimerMode. Replaces impl Default with derive macro. Signed-off-by: Lena Milizé <me@lvmn.org>

We want to check that the timer is what we set it to, and before the condition was backwards. Signed-off-by: Lena Milizé <me@lvmn.org>
