Expand description

Union of indices that can be used to query cardinality of any lower level dimension of a vector with dimension D.

Required Methods§

Source

fn is_d0(&self) -> bool

Returns whether or not the index is of dimension 0; i.e., has type [usize; 0].

Source

fn card<T>(self, vec: &impl NVecCore<D, T>) -> usize

Returns the cardinality of the given vec at this index.

Source

fn card_equality<T>( a: &impl NVecCore<D, T>, b: &impl NVecCore<D, T>, ) -> CardEquality<D>

Returns the cardinality equality of the given vectors a and b at this index.

Source

fn equality<T: PartialEq>( a: &impl NVec<D, T>, b: &impl NVec<D, T>, ) -> Equality<D>

Returns the equality of the given vectors a and b at this index.

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.
