Struct ndarray_einsum_beta::contractors::SingletonContraction

pub struct SingletonContraction<A> {
    method: SingletonMethod,
    op: Box<dyn SingletonContractor<A>>,
}

Holds a Boxed SingletonContractor trait object.

Constructed at runtime based on the number of diagonalized, summed, and permuted axes in the input. Reimplements the SingletonContractor trait by delegating to the inner object.

For example, the contraction iij->i will be performed by assigning a Boxed DiagonalizationAndSummation to op. The contraction ijk->kij will be performed by assigning a Boxed Permutation to op.

Fields

method: SingletonMethod

op: Box<dyn SingletonContractor<A>>
