Detailed Description

Provides transformations for tuples.

This namespace contains transformations that can be used to manipulate tuple types.

Function Documentation

first_element()

template<typename T >

auto docwire::tuple_utils::first_element

(

T &&

tuple

)

Returns the first element of a tuple.

Parameters

tuple

The tuple to return the first element of.

Returns

The first element of the tuple.

Definition at line 109 of file tuple_utils.h.

last_element()

template<typename T >

auto docwire::tuple_utils::last_element

(

T &&

tuple

)

Returns the last element of a tuple.

Parameters

tuple

The tuple to return the last element of.

Returns

The last element of the tuple.

Definition at line 130 of file tuple_utils.h.

remove_first()

template<typename T >

auto docwire::tuple_utils::remove_first

(

T &&

tuple

)

Removes the first element from a tuple.

This function provides a way to remove the first element from a tuple, resulting in a new tuple with the remaining elements.

Parameters

tuple

The tuple to remove the first element from.

Returns

The new tuple with the first element removed.

Definition at line 64 of file tuple_utils.h.

remove_last()

template<typename T >

auto docwire::tuple_utils::remove_last

(

T &&

tuple

)

Removes the last element from a tuple.

This function provides a way to remove the last element from a tuple, resulting in a new tuple with the remaining elements.

Parameters

tuple

The tuple to remove the last element from.

Returns

The new tuple with the last element removed.

Definition at line 88 of file tuple_utils.h.

subrange()

template<std::size_t Start, std::size_t Length, typename... Ts>

auto docwire::tuple_utils::subrange

(

const std::tuple< Ts... > &

tuple

)

Returns subrange of a tuple.

Parameters

t	The tuple to return the subrange of.

Template Parameters

Start	The start index of the subrange.
Length	The length of the subrange.

Returns

The subrange of the tuple.
