Assertions for numeric values not already handled by crate::prelude::PartialEqAssertions and crate::prelude::PartialOrdAssertions.

Required Methods

fn is_zero(self) -> Self

Fails if actual is not equal to the additive identity.

fn is_additive_identity(self) -> Self

fn is_one(self) -> Self

Fails if actual is not equal to the multiplicative identity.

fn is_multiplicative_identity(self) -> Self

fn is_negative(self) -> Self

where T: Signed,

fn is_positive(self) -> Self

where T: Signed,

fn is_close_to(self, expected: T, allowed_deviation: T) -> Self

where T: PartialOrd + Clone,

Fails if actual is not in the range [expected - allowed_deviation, expected + allowed_deviation].

fn is_nan(self) -> Self

where T: Float,

fn is_finite(self) -> Self

where T: Float,

fn is_infinite(self) -> Self

where T: Float,

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.
