Struct simd_adler32::Adler32

pub struct Adler32 {
    pub(crate) a: u16,
    pub(crate) b: u16,
    pub(crate) update: Adler32Imp,
}

Fields

a: u16

b: u16

update: Adler32Imp

Implementations

impl Adler32

pub fn new() -> Self

Constructs a new Adler32.

Potential overhead here due to runtime feature detection although in testing on 100k and 10k random byte arrays it was not really noticeable.

Examples

use simd_adler32::Adler32;

let mut adler = Adler32::new();

pub fn from_checksum(checksum: u32) -> Self

Constructs a new Adler32 using existing checksum.

Potential overhead here due to runtime feature detection although in testing on 100k and 10k random byte arrays it was not really noticeable.

Examples

use simd_adler32::Adler32;

let mut adler = Adler32::from_checksum(0xdeadbeaf);

pub fn write(&mut self, data: &[u8])

Computes hash for supplied data and stores results in internal state.

pub fn finish(&self) -> u32

Returns the hash value for the values written so far.

Despite its name, the method does not reset the hasher’s internal state. Additional writes will continue from the current value. If you need to start a fresh hash value, you will have to use reset.

pub fn reset(&mut self)

Resets the internal state.
