Struct RollSumIncr 

pub struct RollSumIncr { /* private fields */ }

Incrimental instance of RollSum

Performance note: Bup’s Roll sum algorithm requires tracking the entire window. As a result, this includes a circular buffer which all inputs are copied through. If your use case allows it, use the non-incrimental variant for improved performance.

Implementations

impl RollSumIncr

pub fn digest(&self) -> u32

pub fn roll_byte(&mut self, ch: u8)

pub fn at_split(&self) -> bool

Trait Implementations

impl ChunkIncr for RollSumIncr

fn push(&mut self, data: &[u8]) -> Option<usize>

The data “contained” within a implimentor of this trait is the history of all data slices passed to feed.

fn iter_slices<'a>(self, data: &'a [u8]) -> IterSlices<'a, Self>

where Self: Sized,

Given a ChunkIncr and a single slice, return a list of slices chunked by the chunker.

fn iter_slices_strict<'a>(self, data: &'a [u8]) -> IterSlicesStrict<'a, Self>

where Self: Sized,

Given a ChunkIncr and a single slice, return a list of slices chunked by the chunker. Does not return the remainder (if any) in the iteration. Use [IterSlices::take_rem()] or IterSlices::into_parts() to get the remainder.

impl Clone for RollSumIncr

fn clone(&self) -> RollSumIncr

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RollSumIncr

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for RollSumIncr

fn default() -> Self

Returns the “default value” for a type.

impl From<&RollSum> for RollSumIncr

fn from(params: &RollSum) -> Self

Converts to this type from the input type.

impl PartialEq for RollSumIncr

fn eq(&self, other: &RollSumIncr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
