void hook_outcome_copy_construction(T *, U &&, V &&) noexcept

Removed in Outcome v2.2.0, unless OUTCOME_ENABLE_LEGACY_SUPPORT_FOR is set to less than 220 to enable emulation. Use on_outcome_copy_construction(T *, U &&, V &&) noexcept instead in new code.

One of the constructor hooks for basic_outcome<T, EC, EP, NoValuePolicy> , generally invoked by the converting copy constructors of basic_outcome (NOT the standard copy constructor) which consume two arguments. See each constructor’s documentation to see which specific hook it invokes.

Overridable: By Argument Dependent Lookup.

Requires: Nothing.
