Trait Scalar 

pub trait Scalar:
    Add<Output = Self>
    + Sub<Output = Self>
    + Mul<Output = Self>
    + Div<Output = Self>
    + Neg<Output = Self>
    + PartialOrd
    + Debug
    + Copy
    + 'static {
    // Required methods
    fn zero() -> Self;
    fn one() -> Self;
    fn from_usize(n: usize) -> Self;
}

A scalar type suitable for arc-length, parameter, and distance computations.

Requires arithmetic operations (Add, Sub, Mul, Div, Neg), PartialOrd, Debug, Copy, and 'static bounds. Manual implementations are provided for f32 and f64.

Required Methods

fn zero() -> Self

Returns the additive identity (0.0).

fn one() -> Self

Returns the multiplicative identity (1.0).

fn from_usize(n: usize) -> Self

Cast a usize value to this scalar type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
