1// src/traits/infinity.rs : `Infinity`
2
3/// Trait defining class method `infinity() : T` that creates an instance of
4/// the implementing type that is conceptually (or actually) infinity.
5///
6/// # Additional Implementations on Foreign Types
7///
8/// ## Built-in Types
9///
10/// If the feature `"implement-Infinity-for-built_ins"`
11/// is defined (as it is by `"default"`), then this is also implemented
12/// for the following types:
13/// - [`f32`];
14/// - [`f64`];
