Expand description

A trait for approximate equality comparisons.

Required Associated Types§

source

type Margin: Copy + Default

This type type defines a margin within which two values are to be considered approximately equal. It must implement Default so that approx_eq() can be called on unknown types.

Required Methods§

source

fn approx_eq<M>(self, other: Self, margin: M) -> bool
where M: Into<Self::Margin>,

This method tests that the self and other values are equal within margin of each other.

Provided Methods§

source

fn approx_ne<M>(self, other: Self, margin: M) -> bool
where M: Into<Self::Margin>,

This method tests that the self and other values are not within margin of each other.

Object Safety§

This trait is not object safe.
