Struct git_repository::object::blob::diff::Platform

pub struct Platform<'old, 'new> {
    pub old: Object<'old>,
    pub new: Object<'new>,
    pub algo: Algorithm,
}

A platform to keep temporary information to perform line diffs on modified blobs.

Fields

old: Object<'old>

The previous version of the blob.

new: Object<'new>

The new version of the blob.

algo: Algorithm

The algorithm to use when calling imara_diff::diff(). This value is determined by the diff.algorithm configuration.

Implementations

impl<'old, 'new> Platform<'old, 'new>

pub fn from_ids( previous_id: &Id<'old>, new_id: &Id<'new> ) -> Result<Platform<'old, 'new>, Error>

Produce a platform for performing various diffs after obtaining the object data of previous_id and new_id.

Note that these objects are treated as raw data and are assumed to be blobs.

impl<'old, 'new> Platform<'old, 'new>

pub fn lines<FnH, E>(&self, process_hunk: FnH) -> Result<(), E>where FnH: FnMut(Change<'_, '_>) -> Result<(), E>, E: Error,

Perform a diff on lines between the old and the new version of a blob, passing each hunk of lines to process_hunk. The diffing algorithm is determined by the diff.algorithm configuration.

Note that you can invoke the diff more flexibly as well.

pub fn line_counts(&self) -> Counter<()>

Count the amount of removed and inserted lines efficiently.

pub fn line_tokens(&self) -> InternedInput<&[u8]>

Return a tokenizer which treats lines as smallest unit for use in a diff operation.

The line separator is determined according to normal git rules and filters.
