carb::cpp20

Namespace for backports of C++20 features.

Detailed Description

Namespace for C++14 compatible versions of some C++20 STL classes and functions.

Classes

• carb::cpp20::counting_semaphore: Counted semaphore wrapper class.

Enums

• carb::cpp20::endian: Indicates the endianness of all scalar types for the current system.

Functions

• carb::cpp20::bit_cast: Re-interpets the bits src as type To.

• carb::cpp20::bit_ceil: Finds the smallest integral power of two not less than the given value.

• carb::cpp20::bit_floor: Finds the largest integral power of two not greater than the given value.

• carb::cpp20::countr_zero: Returns the number of consecutive 0 bits in the value of val, starting from the least significant bit.

• carb::cpp20::has_single_bit: Checks if a given value is an integral power of 2.

• carb::cpp20::popcount: Returns the number of 1 bits in the value of x.

Typedefs

• carb::cpp20::binary_semaphore: Alias for a counting semaphore that can only be acquired by one caller at a time.
