fn new(poly u64) &Crc64

new creates a Crc64 polynomial.

fn sum(b []u8) u64

sum calculates the CRC-64 checksum of b by using the ECMA polynomial.

fn sum_with_poly(poly u64, b []u8) u64

sum_with_poly calculates the CRC-64 checksum of b for the provided polynomial.

fn (c &Crc64) update_state(state u64, b []u8) u64

update_state updates an internal CRC state with the bytes in b. For CRC-64-ECMA-182, use state 0 for a new stream.

fn (c &Crc64) checksum(b []u8) u64

checksum returns the CRC-64 checksum of data b by using the polynomial represented by c's table.

fn (c &Crc64) update(crc u64, b []u8) u64

update returns the updated CRC-64 checksum for b, starting from crc. Use crc = 0 for a fresh checksum, or pass a previous result to continue streaming.
