Struct Segment

    pub path: Option<String>,

    pub destination: String,
    pub start: String,

    pub starts: Starts,
    pub known_only: bool,
    pub targets: Option<Starts>,
}

An edge searched on the graph index rather than joined: a quantified edge, or the edge of a path with a path variable, a selector or a mode. It is a relation of paths, named var, with the columns of super::path_search: the path’s first and last node, its length, and its nodes and edges.

Fields

var: String

The relation’s name: the path variable, or an unnamed one.

path: Option<String>

The path variable, if the path has one.

edges: TableReference

The edge table, and its source and destination columns.

source: String

destination: String

start: String

The node variables at its two ends, and their keys.

start_key: VarColumn

end: String

end_key: VarColumn

direction: Direction

quantifier: Quantifier

selector: Selector

mode: Mode

fixed: bool

A fixed-length edge expanded through the index, not a searched path.

starts: Starts

known_only: bool

Whether the index’s nodes are the start node’s table’s keys, so a start that is not a node of the index is no node at all.

targets: Option<Starts>

The keys the last node can have, when they are known: the values its conditions name (Starts::Node: it is bound, see Usage::bound), or the keys an earlier segment reached. The search’s targets.
