Trait for testing approximate equality

Required Methods

fn approx_epsilon() -> Eps

Default epsilon value

fn approx_eq_eps(&self, other: &Self, approx_epsilon: &Eps) -> bool

Returns true if this object is approximately equal to the other one, using a provided epsilon value.

Provided Methods

fn approx_eq(&self, other: &Self) -> bool

Returns true if this object is approximately equal to the other one, using the approx_epsilon epsilon value.

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.
