Enum DiffAlgorithm

pub enum DiffAlgorithm {
    Rsync020,
    Bidiff1,
}

Algorithms available for generating binary diffs.

Each algorithm offers different tradeoffs between patch size, generation speed, and application speed.

Example

use darkwing_diff::{diff, DiffAlgorithm, CompressAlgorithm};

// Use rsync for fast diffing of similar files
let rsync_patch = diff(
    b"original",
    b"modified",
    DiffAlgorithm::Rsync020,
    CompressAlgorithm::None
)?;

// Use bidiff for potentially smaller patches
let bidiff_patch = diff(
    b"original",
    b"modified",
    DiffAlgorithm::Bidiff1,
    CompressAlgorithm::Zstd
)?;

Variants

Rsync020

Fast-rsync algorithm version 0.2.0. Optimized for files that are mostly similar.

Bidiff1

Bidirectional diff algorithm version 1. May produce smaller patches for very different files.

Trait Implementations

impl Archive for DiffAlgorithm

type Archived = ArchivedDiffAlgorithm

The archived representation of this type.

type Resolver = DiffAlgorithmResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for DiffAlgorithm

fn clone(&self) -> DiffAlgorithm

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DiffAlgorithm

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<DiffAlgorithm, __D> for Archived<DiffAlgorithm>

fn deserialize( &self, deserializer: &mut __D, ) -> Result<DiffAlgorithm, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for DiffAlgorithm

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

Formats the value using the given formatter.

impl Hash for DiffAlgorithm

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DiffAlgorithm

fn eq(&self, other: &DiffAlgorithm) -> 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.

impl<__S: Fallible + ?Sized> Serialize<__S> for DiffAlgorithm

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Copy for DiffAlgorithm

impl Eq for DiffAlgorithm

impl StructuralPartialEq for DiffAlgorithm
