Struct ChangeDelta 

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

Describes a change-delta representing replaced content between original and revised sequences.

Implementations

impl<T> ChangeDelta<T>

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

Creates a new ChangeDelta with the given source and target chunks.

pub fn delta(&self) -> &Delta<T>

Returns a reference to the underlying inner Delta.

pub fn into_delta(self) -> Delta<T>

Consumes self and returns the inner Delta.

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

Returns a reference to the source chunk.

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

Returns a reference to the target chunk.

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

where T: Clone + PartialEq,

Applies this change delta to the target vector.

Replaces the element range at the source chunk’s position with the target chunk’s lines.

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

where T: Clone + PartialEq,

Restores (un-applies) this change delta on the target sequence.

Replaces the element range at the target chunk’s position with the original source lines.

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

where T: Clone + PartialEq,

Applies the patch with a fuzzy tolerance context offset.

pub fn with_chunks(&self, original: Chunk<T>, revised: Chunk<T>) -> Self

Creates a new ChangeDelta with custom source and target chunks.
