Struct IrSingleLinkPointer 

pub struct IrSingleLinkPointer {
    pub alias: String,
    pub correlation: IrSingleLinkCorrelation,
    pub subquery: IrSelect,
    pub link_properties: Vec<IrLinkProp>,
    pub marker_offset: Option<usize>,
}

A single-valued link included in the output shape. Emitted as a correlated scalar subquery — either a plain FK-column correlation, or, for a junction-backed single link, the same join shape a multi-link uses, just implicitly capped to at most one row per source.

Fields

alias: String

correlation: IrSingleLinkCorrelation

subquery: IrSelect

Nested SELECT producing the linked object.

link_properties: Vec<IrLinkProp>

Extra scalar columns from a junction through type (@prop syntax) — always empty for IrSingleLinkCorrelation::Fk, since a plain FK column has no junction row to read properties from.

marker_offset: Option<usize>

See IrScalarPointer::marker_offset.
