Struct Delta 

pub struct Delta<T> { /* private fields */ }

Represents a single modification delta between a source chunk and a target chunk.

Implementations

impl<T> Delta<T>

pub fn new(delta_type: DeltaType, source: Chunk<T>, target: Chunk<T>) -> Self

Creates a new Delta with the specified type, source, and target chunks.

pub fn source(&self) -> &Chunk<T>

Returns a reference to the source chunk.

pub fn source_mut(&mut self) -> &mut Chunk<T>

Returns a mutable reference to the source chunk.

pub fn target(&self) -> &Chunk<T>

Returns a reference to the target chunk.

pub fn target_mut(&mut self) -> &mut Chunk<T>

Returns a mutable reference to the target chunk.

pub fn delta_type(&self) -> DeltaType

Returns the type of this delta.

pub fn verify_chunk_to_fit_target( &self, target: &[T], ) -> Result<VerifyChunk, PatchError>

where T: PartialEq,

Verifies whether the source chunk of this delta fits the provided target sequence.

pub fn verify_and_apply_to( &self, target: &mut Vec<T>, ) -> Result<VerifyChunk, PatchError>

where T: Clone + PartialEq,

Verifies that the source chunk matches the target sequence and applies the delta in-place if valid.

pub fn apply_to(&self, target: &mut Vec<T>) -> Result<(), PatchError>

where T: Clone + PartialEq,

Applies this delta to the target vector using its source chunk position.

pub fn apply_at( &self, target: &mut Vec<T>, pos: usize, ) -> Result<(), PatchError>

where T: Clone + PartialEq,

Applies this delta to the target vector starting at an explicit position.

pub fn restore(&self, target: &mut Vec<T>) -> Result<(), PatchError>

where T: Clone + PartialEq,

Restores (un-applies) this delta, reverting the target sequence back to its original state.

pub fn apply_fuzzy_to_at( &self, target: &mut Vec<T>, _fuzz: usize, position: usize, ) -> Result<(), PatchError>

where T: Clone + PartialEq,

Applies fuzzy patch matching at a given position with context tolerances. Applies fuzzy patch matching at a given position with context tolerances.

pub fn with_chunks(&self, source: Chunk<T>, target: Chunk<T>) -> Self

Returns a new instance of Delta with customized source and target chunk values.
