Detailed Description

This header provides definitions from the C++ header <tuple>

Definition in file tuple.hpp.

Function Documentation

apply()

template<typename Fn , typename Tuple >

constexpr detail::apply_result_t<Fn, Tuple> bpstd::apply ( Fn &&  fn, Tuple &&  tuple  )

constexpr

Invokes the function fn using the arguments in tuple.

This invokes fn as if it were a call to bpstd::invoke using the arguments in tuple

Parameters

fn	the function to invoke
tuple	the tuple of arguments to pass to fn

Returns

the result from fn

make_from_tuple()

template<typename T , typename Tuple >

constexpr T bpstd::make_from_tuple ( Tuple &&  tuple )

constexpr

Constructs a type T using the arguments in tuple.

Template Parameters

T	the type to construct

Parameters

tuple

the tuple of arguments to pass to T's constructor
