Typedef Documentation

expand_as

template<typename Pack, typename T>

using stellarlib::ext::expand_as = T

Expands a parameter pack into a repeated type.

Template Parameters

Pack	Parameter pack used to drive expansion
T	Type to substitute for each element

is_trivially_relocatable

template<typename T>

using stellarlib::ext::is_trivially_relocatable = std::bool_constant<std::is_trivially_move_constructible_v<T> && std::is_trivially_destructible_v<T>>

Evaluates whether T is eligible for bit-wise relocation.

Template Parameters

T	Type to evaluate

Function Documentation

bit_index()

template<typename T>

auto stellarlib::ext::bit_index ( const T arg )

nodiscardconstexprnoexcept

Calculates the segment index of a bit in an array.

Template Parameters

T	Unsigned integral type of the segment

Parameters

arg	Index of the bit

Returns

Segment index of the bit in the array

bit_mask()

template<typename T>

auto stellarlib::ext::bit_mask ( const T arg )

nodiscardconstexprnoexcept

Calculates the segment mask of a bit in an array.

Template Parameters

T	Unsigned integral type of the segment

Parameters

arg	Index of the bit

Returns

Segment mask of the bit in the array

sequential_id()

template<typename Scope, typename SizeType = std::size_t>

auto stellarlib::ext::sequential_id ( )

nodiscardconstexprnoexcept

Thread-safe sequential ID generator scoped by type.

Template Parameters

Scope	Distinct type used to separate ID sequences
SizeType	Integral type of the ID

Returns

Next ID in the sequence for the given scope

scoped_typeid()

template<typename Scope, typename T, typename SizeType = std::size_t>

auto stellarlib::ext::scoped_typeid ( )

nodiscardconstexprnoexcept

Generates a unique ID per type within a scope.

Template Parameters

Scope	Distinct type used to separate ID spaces
T	Type to retrieve an ID for
SizeType	Integral type of the ID

Returns

Unique ID corresponding to type T within the scope
