pub trait MaxDifference {
// Required method
fn max_diff(self, other: Self) -> f64;
}Expand description
Helper trait for assert_about_equal macro. Returns the max difference between
two vectors of floats. Can also be used for single floats.
§Examples
Compare two floating numbers:
assert!((0.1f64 - 42.1f32.max_diff(42.0f32)) < 1.0e-4f64);Compare two vectors. Returns the maximum difference in the vectors. In this case ~0.1.:
assert!(0.1f64 - vec![42.0, 42.0f32, 1.001f32].max_diff(vec![42.0, 42.1f32, 1.0f32]) < 1.0e-4f64);Compare two arrays. Trait implemented for arrays of length 0-32:
assert!(0.1f64 - [42.0, 42.0f32, 1.001f32].max_diff([42.0, 42.1f32, 1.0f32]) < 1.0e-4f64);Required Methods§
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
