A Theme for the diff

This is to allows some control over what the diff looks like without having to parse it yourself

Required Methods

fn equal_prefix<'this>(&self) -> Cow<'this, str>

The prefix to give lines that are equal

fn delete_prefix<'this>(&self) -> Cow<'this, str>

The prefix to give lines that are being removed

fn insert_prefix<'this>(&self) -> Cow<'this, str>

The prefix to give lines that are being added

fn header<'this>(&self) -> Cow<'this, str>

A header to put above the diff

Provided Methods

fn highlight_insert<'this>(&self, input: &'this str) -> Cow<'this, str>

How to format the text when highlighting it for inserts

fn highlight_delete<'this>(&self, input: &'this str) -> Cow<'this, str>

How to format the text when highlighting it for deletes

fn equal_content<'this>(&self, input: &'this str) -> Cow<'this, str>

How to format unchanged content

fn delete_content<'this>(&self, input: &'this str) -> Cow<'this, str>

How to format bits of text that are being removed

fn insert_line<'this>(&self, input: &'this str) -> Cow<'this, str>

How to format bits of text that are being added

fn line_end<'this>(&self) -> Cow<'this, str>

If a diff line doesn’t end with a newline, what should we insert

fn trailing_lf_marker<'this>(&self) -> Cow<'this, str>

If one of the two strings ends with a newline, and the other does not, insert this character before the newline, and then re-add the newline
