[−][src]Crate crc32c
This crate provides the CRC-32-Castagnoli algorithm.
It provides both a software implementation, and a hardware-optimized one for SSE 4.2.
Example
let message = b"Hello world!"; let crc = crc32c::crc32c(message); assert_eq!(crc, 0x7B_98_E7_51);
Enabling hardware acceleration
If you compile your code with -C target-features=+sse4.2
,
then the hardware-optimized version will be compiled into the code.
Otherwise, the crate will use cpuid
at runtime to detect the
running CPU's features, and enable the appropiate algorithm.
Functions
crc32c | Computes the CRC for the data payload. |
crc32c_append | Computes the CRC for the data payload, starting with a previous CRC value. |
