Struct gix_diff::blob::UnifiedDiffBuilder

pub struct UnifiedDiffBuilder<'a, W, T>
where
    W: Write,
    T: Hash + Eq + Display,
{ /* private fields */ }

Available on crate feature blob only.

A Sink that creates a textual diff in the format typically output by git or gnu-diff if the -u option is used

Implementations

impl<'a, T> UnifiedDiffBuilder<'a, String, T>

where T: Hash + Eq + Display,

pub fn new(input: &'a InternedInput<T>) -> UnifiedDiffBuilder<'a, String, T>

Create a new UnifiedDiffBuilder for the given input, that will return a String.

impl<'a, W, T> UnifiedDiffBuilder<'a, W, T>

where W: Write, T: Hash + Eq + Display,

pub fn with_writer( input: &'a InternedInput<T>, writer: W, ) -> UnifiedDiffBuilder<'a, W, T>

Create a new UnifiedDiffBuilder for the given input, that will writes it output to the provided implementation of Write.

Trait Implementations

impl<W, T> Sink for UnifiedDiffBuilder<'_, W, T>

where W: Write, T: Hash + Eq + Display,

type Out = W

fn process_change(&mut self, before: Range<u32>, after: Range<u32>)

This method is called whenever a diff algorithm finds a change between the two processed input file. A change is a continous subsequence of tokens before that needs to be replaced by a different contious subsequence of tokens after to construct the seconds file from the first.

fn finish(self) -> <UnifiedDiffBuilder<'_, W, T> as Sink>::Out

This function is called after all calls to process_change are complete to obtain the final diff result

fn with_counter(self) -> Counter<Self>

Utility method that constructs a Counter that tracks the total number of inserted and removed tokens in the changes passed to process_change.
