Trait glamour::Scalar

pub trait Scalar: PodValue + PartialOrd + ToRaw<Raw = Self> + FromRaw + AsRaw + Display + Unit<Scalar = Self> + NumOps + NumCast + AbsDiffEq<Epsilon = Self> + From<bool> {
    type Vec2: Vector2<Scalar = Self>;

    // Provided method
    fn try_cast<T2: Scalar>(self) -> Option<T2> { ... }
}

All types that can serve as components of a SIMD type in glam.

This is implemented for f32, f64, i32, u32, i16, u16, i64, and u64.

Required Associated Types

type Vec2: Vector2<Scalar = Self>

The underlying 2D vector type for this scalar (glam::Vec2, glam::DVec2, glam::IVec2, or glam::UVec2).

type Vec3: Vector3<Scalar = Self>

The underlying 3D vector type for this scalar (glam::Vec3, glam::DVec3, glam::IVec3, or glam::UVec3).

type Vec4: Vector4<Scalar = Self>

The underlying 4D vector type for this scalar (glam::Vec4, glam::DVec4, glam::IVec4, or glam::UVec4).

Required Associated Constants

const ZERO: Self

Zero.

const ONE: Self

One.

Provided Methods

fn try_cast<T2: Scalar>(self) -> Option<T2>

Try casting to another scalar type.

The cast always succeeds if the scalars have the same underlying type (i.e., the same Primitive associated type).

The cast fails under the same conditions where num_traits::NumCast::from() fails.

Object Safety

This trait is not object safe.
