Struct Chunk 

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

Represents a contiguous sub-sequence (chunk) of items participating in a diff/patch operation.

Implementations

impl<T> Chunk<T>

pub fn new( position: usize, lines: Vec<T>, change_position: Option<Vec<usize>>, ) -> Self

Creates a new Chunk with a starting position, lines, and optional positions of modified lines.

pub fn with_lines(position: usize, lines: Vec<T>) -> Self

Convenience constructor creating a Chunk without granular line-change tracking indices.

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

where T: PartialEq,

Verifies that this chunk’s saved lines match the corresponding region in the target slice.

pub fn verify_chunk_at( &self, target: &[T], fuzz: usize, position: usize, ) -> Result<VerifyChunk, PatchError>

where T: PartialEq,

Verifies that this chunk matches the target sequence starting at position, taking fuzz context into account.

pub fn position(&self) -> usize

Returns the zero-based start position of this chunk.

pub fn lines(&self) -> &[T]

Returns a slice reference to the chunk’s lines.

pub fn lines_mut(&mut self) -> &mut Vec<T>

Returns a mutable slice reference to the chunk’s lines.

pub fn set_lines(&mut self, lines: Vec<T>)

Sets or replaces the lines stored inside this chunk.

pub fn change_position(&self) -> Option<&[usize]>

Returns an optional slice reference to the change position indices, if present.

pub fn len(&self) -> usize

Returns the number of lines contained in this chunk.

pub fn size(&self) -> usize

Alias method for len matching common Java/C# diff library APIS.

pub fn is_empty(&self) -> bool

Returns true if this chunk contains no lines.

pub fn last(&self) -> usize

Returns the zero-based index of the last line in the chunk (if non-empty).
