Trait SameNumberOfColumns

pub trait SameNumberOfColumns<D1, D2>: DimEq<D1, D2> + DimEq<D2, D1>
where
    D1: Dim,
    D2: Dim,
{
    type Representative: Dim;

    // Provided method
    fn representative(d1: D1, d2: D2) -> Option<Self::Representative> { ... }
}

Constrains D1 and D2 to be equivalent. They are both assumed to be the number of columns of a matrix.

Required Associated Types

type Representative: Dim

This is either equal to D1 or D2, always choosing the one (if any) which is a type-level constant.

Provided Methods

fn representative(d1: D1, d2: D2) -> Option<Self::Representative>

Returns a representative dimension instance if the two are equal, otherwise None.

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.
