Trait Constraint 

pub trait Constraint<T> {
    const NAME: &'static str;

    // Required method
    fn satisfied(value: &T) -> bool;
}

A constraint that a Safe<T, C> value must satisfy.

Implement this for a zero-sized marker type C to make it usable with Safe::try_new and the crate::safe! macro.

Required Associated Constants

const NAME: &'static str

Stable, human-readable identifier (e.g. "!nan").

Required Methods

fn satisfied(value: &T) -> bool

Returns true if value satisfies the constraint.

Dyn Compatibility

This trait is not dyn compatible.

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

Implementors

impl Constraint<f64> for Finite

const NAME: &'static str = "!nan,!inf"

impl Constraint<f64> for NonInf

const NAME: &'static str = "!inf"

impl Constraint<f64> for NonNan

const NAME: &'static str = "!nan"
