Trait NormInfinity 

pub trait NormInfinity<F = f64> {
    // Required method
    fn norm_infinity(&self) -> F;
}

‖x‖_∞ = maxᵢ |xᵢ|. Used by first-order optimality stopping rules (e.g. ‖∇f‖_∞ ≤ tol).

F defaults to f64; see NormSquared for the rationale.

Required Methods

fn norm_infinity(&self) -> F

Compute maxᵢ |xᵢ| as F.

Returns NaN if any component is NaN, and zero for an empty input.

Dyn Compatibility

This trait is dyn compatible.

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