The standard f64 and f32 types support conversion from integer types for which the conversion will not lose precision, as well as from bool. This commit adds that same support to OrderedFloat.

The standard `f64` and `f32` types support conversion from integer types
for which the conversion will not lose precision, as well as from `bool`.
This commit adds that same support to `OrderedFloat`.

I see that the build failed because From<bool> for f64 and f32 is only supported in 1.68.0 and later. I can think of the following ways to fix that:

  • Bump the minimum Rust version to 1.68.
  • Define these conversion for OrderedFloat only in 1.68 and later.
  • Implement the conversions in OrderedFloat so that they don't try to use the underlying conversions for f64 and f32 but just implement them themselves.

Any preference?

Implement the conversions in OrderedFloat so that they don't try to use the underlying conversions for f64 and f32 but just implement them themselves.

Let’s use this option.

Support bool to OrderedFloat conversions for Rust before 1.68.0.

The Rust standard library only implemented `From<bool>` for `f32` and `f64`
starting from version 1.68.0, so to support earlier versions this commit
implements those conversions by hand.
