Struct adler32::RollingAdler32 [] [src]

pub struct RollingAdler32 { /* fields omitted */ }

A rolling version of the Adler32 hash, which can 'forget' past bytes.

Calling remove() will update the hash to the value it would have if that past byte had never been fed to the algorithm. This allows you to get the hash of a rolling window very efficiently.

Methods

impl RollingAdler32
[src]

Creates an empty Adler32 context (with hash 1).

Creates an Adler32 context with the given initial value.

Convenience function initializing a context from the hash of a buffer.

Returns the current hash.

Removes the given byte that was fed to the algorithm size bytes ago.

Feeds a new byte to the algorithm to update the hash.

Feeds a vector of bytes to the algorithm to update the hash.
