Enum IrMultiLinkValueSource 

pub enum IrMultiLinkValueSource {
    CteRef(String),
    Select(Box<IrSelect>),
    PathSelect(Box<IrPathSelect>),
    Function(Box<IrFunctionSelect>),
    Union(Box<IrMultiLinkValues>, Box<IrMultiLinkValues>),

}

How to obtain the target object IDs for a multi-link mutation.

Variants

CteRef(String)

Reference to a named CTE: FROM "cte_name".

Select(Box<IrSelect>)

A regular schema SELECT (use source table + filter to get ids).

PathSelect(Box<IrPathSelect>)

A path-traversal SELECT (root + joins, final result is the id).

Function(Box<IrFunctionSelect>)

members := account_of_transaction() — the rows an object-returning function yields.

Union(Box<IrMultiLinkValues>, Box<IrMultiLinkValues>)

a union b — combine two target sets (e.g. distinct-typed adds, or an existing-select add alongside a same-batch forward-referenced insert).

Asserted

prices := assert_distinct(…) — the targets the inner value names, checked before they become junction rows. fn_name is a _pylon assert over anyarray; the ids go through it as a uuid[], so the inner value is evaluated once even when it contains an insert.

Fields

fn_name: String

inner: Box<IrMultiLinkValues>

message: Option<IrExpr>

message := … — raised in place of the assert’s own text.
