Struct gearhash::Hasher

pub struct Hasher<'t> { /* fields omitted */ }

Gear hash state. Processes bytes to find chunk boundaries.

Methods

impl<'t> Hasher<'t>

pub fn new(table: &'t Table) -> Self

Create a new hasher with the given table.

pub fn update(&mut self, buf: &[u8])

Update the hash state by processing all the bytes in the given slice.

pub fn is_match(&self, mask: u64) -> bool

Match the current hash state against the given mask.

Returns true if hash & mask == 0, false otherwise.

pub fn next_match(&mut self, buf: &[u8], mask: u64) -> Option<usize>

Processes the given byte slice until a match is found for the given mask.

If a match is found before the end of the byte slice, it returns the number of bytes processed. If no match has been found, it returns None.

pub fn get_hash(&self) -> u64

Retrieve the current hash value.

pub fn set_hash(&mut self, hash: u64)

Set the hash value to the given integer.
