Available on crate feature unstable-enable only.
Expand description

Trait to allow rings to provide specialized implementations for inner products, i.e. the sums sum_i a[i] * b[i].

§Availability

This API is marked as unstable and is only available when the unstable-enable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Required Methods§

Source

fn inner_product_ref<'a, I: Iterator<Item = (&'a Self::Element, &'a Self::Element)>>( &self, els: I, ) -> Self::Element
where Self::Element: 'a, Self: 'a,

Computes the inner product sum_i lhs[i] * rhs[i].

Source

fn inner_product_ref_fst<'a, I: Iterator<Item = (&'a Self::Element, Self::Element)>>( &self, els: I, ) -> Self::Element
where Self::Element: 'a, Self: 'a,

Computes the inner product sum_i lhs[i] * rhs[i].

Source

fn inner_product<I: Iterator<Item = (Self::Element, Self::Element)>>( &self, els: I, ) -> Self::Element

Computes the inner product sum_i lhs[i] * rhs[i].

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.
