Struct ScalarLinkField 

pub struct ScalarLinkField {
    pub name: String,
    pub outer_alias: String,
    pub links: Vec<String>,
    pub column: String,
    pub resolved: Option<ScalarLinkResolved>,
}

A scalar link traversal projection field. Like via_link on NestedProjection, the planner cannot resolve link names (it never touches the catalog), so resolved is None out of the planner and is filled in by the executor before assembly.

Fields

name: String

Output column name (the field alias, or the dotted source spelling).

outer_alias: String

The outer scan alias the path starts from (o).

links: Vec<String>

Declared to-one link names in traversal order (["user", "company"]).

column: String

The column read on the final target (name).

resolved: Option<ScalarLinkResolved>

Filled by the executor’s catalog resolution; None out of the planner.
