Struct Lowered 

pub struct Lowered {
    pub sources: Vec<Source>,
    pub segments: Vec<Segment>,
    pub aliases: Vec<Alias>,
    pub branches: Vec<Vec<Join>>,
    pub union: bool,
    pub conditions: Vec<String>,
    pub columns: String,
}

A pattern resolved against a graph: what to scan and join.

Fields

sources: Vec<Source>

One per variable, in order of appearance, except the edges searched as segments.

segments: Vec<Segment>

The edges searched on the graph index, joined to their end nodes in every branch. A segment’s Starts::After names an earlier one.

aliases: Vec<Alias>

The nodes whose sources are not joined: their keys are segment columns.

branches: Vec<Vec<Join>>

One per orientation of the undirected edges: the joins of each branch of the UNION ALL (one branch when every edge has a direction).

union: bool

Whether the match planned as joins would be a UNION ALL: it has an undirected fixed edge, joined or not.

conditions: Vec<String>

The pattern’s conditions as written: in elements, then after the paths.

columns: String

The COLUMNS list as written.
