Enum Op 

pub enum Op {
    Equal {
        a: usize,
        b: usize,
    },
    Delete {
        a: usize,
    },
    Insert {
        b: usize,
    },
    Move {
        a: usize,
        b: usize,
    },
    Replace {
        a: Range<usize>,
        b: Range<usize>,
    },
}

One step of an edit script.

Scripts list ops in output order: the b indices of Equal, Insert, Move and Replace ops appear in increasing order, so walking the script reconstructs b. Delete ops sit at their position relative to the surviving a items.

Variants

Equal

a[a] is kept and becomes b[b].

Fields

a: usize

Index into a.

b: usize

Index into b.

Delete

a[a] is removed.

Fields

a: usize

Index into a.

Insert

b[b] is new.

Fields

b: usize

Index into b.

Move

a[a] and b[b] have equal keys but were not matched in order: the item travels.

Fields

a: usize

Index into a.

b: usize

Index into b.

Replace

The items a[a] are replaced by (morphed into) the items b[b].

Fields

a: Range<usize>

Range of a.

b: Range<usize>

Range of b.
