Enum DiffKind 

pub enum DiffKind {
    Equal,
    Add,
    Remove,
}

How a line relates to the other side of the diff.

Variants

Equal

Present in both inputs, unchanged.

Add

Present only in the revision.

Remove

Present only in the original.

Implementations

impl DiffKind

pub fn as_str(self) -> &'static str

The wire encoding: a single character, so the JS side can rebuild the label without a table lookup.
