A generic length trait.

A more specific number type is needed for CSS handling. In most cases f32 is what you need, but sometimes fixed-pointer types are preferred.

Required Associated Types

type Hashable: Eq + Hash + Debug

A target type used for hashing.

Required Methods

fn to_hashable(&self) -> Self::Hashable

Convert to the hashable type.

fn is_normal(&self) -> bool

The number is normal (a.k.a. f32::is_normal) or not.

fn from_f32(v: f32) -> Self

Convert from f32.

fn to_f32(self) -> f32

Convert to f32.

fn from_i32(v: i32) -> Self

Convert from i32.

Provided Methods

fn mul_f32(self, v: f32) -> Self

Multiply f32.

fn div_f32(self, v: f32) -> Self

Divide f32.

fn mul_i32(self, v: i32) -> Self

Multiply i32.

fn div_i32(self, v: i32) -> Self

Divide i32.

fn upper_bound(self, v: Self) -> Self

Limit the number with an upper bound.

fn lower_bound(self, v: Self) -> Self

Limit the number with an lower bound.

Dyn Compatibility

This trait is not dyn compatible.

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