Struct CreateLinkExpr 

pub struct CreateLinkExpr {
    pub owner: String,
    pub name: String,
    pub target: String,
    pub local_key: String,
    pub target_key: String,
}

A persistent entity-link declaration, written either as a bare statement (link <Owner>.<name> -> <Target> on <local> = <target>) or as an alter <Owner> add link <name> -> <Target> on <local> = <target> action. The on <local> = <target> clause reads “the owner’s local_key equals the target’s target_key”. Cardinality (ToOne/ToMany) is NOT written here: it is derived by Catalog::create_link from whether target_key is backed by a unique index on the target.

Fields

owner: String

The type the link is declared on (traversed as <alias>.<name>).

name: String

Traversal name, unique per owner type.

target: String

Target type the link resolves to.

local_key: String

Column on the owner supplying the join value.

target_key: String

Column on the target matched against local_key.
