Struct UnifiedDiff

pub struct UnifiedDiff<'a, T, D>
where
    T: Hash + Eq + AsRef<[u8]>,
    D: ConsumeHunk,
{ /* 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, and passes it in full to a consumer.

Implementations

impl<'a, T, D> UnifiedDiff<'a, T, D>

where T: Hash + Eq + AsRef<[u8]>, D: ConsumeHunk,

pub fn new( input: &'a InternedInput<T>, consume_hunk: D, newline_separator: NewlineSeparator<'a>, context_size: ContextSize, ) -> Self

Create a new instance to create unified diff using the lines in input, which also must be used when running the diff algorithm. context_size is the amount of lines around each hunk which will be passed to consume_hunk.

consume_hunk is called for each hunk in unified-diff format, as created from each line separated by newline_separator.

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 files. A change is a continuous subsequence of tokens before that needs to be replaced by a different continuous subsequence of tokens after to construct the second file from the first.

fn finish(self) -> Self::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.
