Overview

template<uint32_t(*)(const void *, size_t, uint32_t) kChecksumFunction>
class pw::checksum::Crc32Impl< kChecksumFunction >

Calculates the CRC32 for all data passed to Update.

This class is more efficient than the CRC32 C functions since it doesn't finalize the value each time it is appended to.

Public Member Functions
void	Update (span< const std::byte > data)
	Updates the CRC with the provided data.

void	Update (std::byte data)
	Updates the CRC with the provided byte.

uint32_t	value () const
	Returns the value of the CRC32 for all data passed to Update.

void	clear ()
	Resets the CRC to the initial value.

Static Public Member Functions
static uint32_t	Calculate (span< const std::byte > data)
	Calculates the CRC32 for the provided data and returns it as a uint32_t.
