Enum Binding 

pub enum Binding<'a> {
    Bound {
        raw: RawRef<'a>,
        targets: Vec<ObjectId>,
    },
    Unresolved {
        raw: RawRef<'a>,
    },
}

What one RawRef bound to in the model — the graph-ready outcome of resolution, as data.

Variants

Bound

The reference matched at least one model object. targets holds the graph-node identities of every candidate: an unqualified [Name] can bind a measure and a home-table column at once, because a lexer cannot tell row context from filter context.

Fields

raw: RawRef<'a>

The reference as written.

targets: Vec<ObjectId>

The objects the reference keeps alive.

Unresolved

The reference matched nothing — a stale expression, a typo, a renamed object, or a built-in function. Never an error: the graph layer decides what an unresolvable reference means (typically: ignore).

Fields

raw: RawRef<'a>

The reference as written, for diagnostics.

Implementations

impl Binding<'_>

pub fn targets(&self) -> &[ObjectId]

The bound objects, empty for an unresolved reference.

pub fn is_unresolved(&self) -> bool

True when the reference matched nothing.

Trait Implementations
