Deprecated. Use of this entity is allowed but discouraged.

Description

Historical note: Abseil once provided implementations of these abstractions for platforms that had not yet provided them. Those platforms are no longer supported. New code should simply use the the ones from std directly.

Exception specification

This function is potentially-throwing unless noexcept(std::apply(std::declval<F>(), std::declval<T>())).

Return Value

The result of invoking f with the tuple's elements.

Parameters

Name

Description

The callable to invoke.
