Trait Numeric 

pub trait Numeric:
    Copy
    + PartialOrd
    + Display {
    const KIND: &'static str;

    // Required methods
    fn read(raw: &str) -> Option<(Self, Value)>;
    fn divisible_by(self, step: Self) -> bool;
}

The two number kinds a document can ask one flag for.

A trait rather than two copies of Bounds and its rules: the comparisons are the same sentence in both, and only reading a value out of an argument and dividing by one differ. It is public because Bounds is, and there is no third kind to implement it for — i64 and f64 are what OpenAPI’s integer and number are.

Required Associated Constants

const KIND: &'static str

What a refusal calls this kind.

Required Methods

fn read(raw: &str) -> Option<(Self, Value)>

This kind read out of one argument, with the JSON it goes out as.

One step, because the two can disagree: a float that parses but is not finite is not a number JSON carries, and “is not a number” is the honest answer rather than a null on the wire.

fn divisible_by(self, step: Self) -> bool

multipleOf: whether dividing by step leaves a whole number.

Dyn Compatibility

This trait is not dyn compatible.

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