Struct Source 

pub struct Source {
    pub var: String,
    pub table: TableReference,
    pub columns: Option<Vec<(String, String)>>,
    pub joined: bool,
}

What a variable reads: an element table (or the graph’s nodes table), all its columns or columns as (column, property name).

Fields

var: String

table: TableReference

columns: Option<Vec<(String, String)>>

None: every column, under its own name.

joined: bool

Whether the match joins it: a node whose key is a segment’s column (Lowered::aliases) is read only for its start keys, if at all.
