Synopsis

Declared in <folly/algorithm/simd/find_first_of.h>

template<
    typename Vector,
    typename Scalar>
class composite_finder_first_of;

Description

A find-first-of finder which composes a vector finder with a scalar finder.

A vector finder requires a scalar finder for not-implemented-architecture and for near-end-of-input. This combinator producers a finder which uses the vector finder where possible and otherwise falls back to the scalar finder.
