Struct Location

pub struct Location<Name> {
    pub descendant: Name,
    pub distance: u64,
}

The position of one node in the graph relative their known descendant. This structure is relevant when the IdMap is lazy. Assuming that all parents of merges and all heads are known then any node can be represented as their first descendant and the distance to that descendant.

Example: 0 - a - b - c In this example our initial commit is 0, then we have a the first commit, b second, c third. { descendant: c, distance: 1, } => [b]

Fields

descendant: Name

distance: u64
