Trait FloatClass 

pub trait FloatClass: Real {
    // Required methods
    fn is_finite(self) -> bool;
    fn is_nan(self) -> bool;
    fn is_infinite(self) -> bool;
    fn is_normal(self) -> bool;

Floating-point classification.

Required Methods

fn is_finite(self) -> bool

Returns true if self is neither infinite nor NaN.

fn is_nan(self) -> bool

Returns true if self is NaN.

fn is_infinite(self) -> bool

Returns true if self is positive or negative infinity.

fn is_normal(self) -> bool

Returns true if self is neither zero, infinite, subnormal, nor NaN.

fn is_subnormal(self) -> bool

Returns true if self is subnormal (denormal).

fn is_sign_negative(self) -> bool

Returns true if the sign bit is negative.

fn is_sign_positive(self) -> bool

Returns true if the sign bit is positive (or zero).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
