Detailed Description

template<std::size_t N>
class constexpr_bitset< N >

A bitset structure that can be initialized at compile-time and read at both compile-time and run-time.

Parameters

N	number of bits that this set can store.

Member Function Documentation

set()

template<std::size_t N>

constexpr void constexpr_bitset< N >::set ( std::size_t  idx )

inlineconstexpr

Set bit at given index.

Parameters

idx	Index to set. Counting starts from zero, and must be less than N.

set_n()

template<std::size_t N>

constexpr void constexpr_bitset< N >::set_n ( std::size_t  idx, std::size_t  count  )

inlineconstexpr

Set a range of bits.

Parameters

idx	First bit to set
count	Count of bits to set

test()

template<std::size_t N>

constexpr bool constexpr_bitset< N >::test ( std::size_t  idx ) const

inlineconstexpr

Test bit at given index.

Parameters

idx	Index to read. Counting starts from zero, and must be less than N.

Returns

Whether the given bit is set.
