Trait ComponentMulAssign 

pub trait ComponentMulAssign {
    // Required method
    fn component_mul_assign(&mut self, other: &Self);
}

In-place componentwise multiplication self[i] ← self[i] · other[i]. CMA-ES uses this to apply the diagonal D (sqrt-eigenvalue) factor: the sampling step y_k = B D z_k is z.component_mul_assign(&d); y = B.matvec(&z), and the conjugate-path step C^{−1/2} v = B (1/d ⊙ Bᵀv) is the same pattern with 1/d.

Required Methods

fn component_mul_assign(&mut self, other: &Self)

Multiply self[i] by other[i] for every i, in place.

Dyn Compatibility

This trait is not dyn compatible.

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