Struct Via 

pub struct Via {
    pub path: Path,
}

A multi-step relation path.

A HasMany or HasOne declared with #[has_many(via = a.b)] reaches its target by following a path of existing relations rather than pairing with a single BelongsTo. The path is resolved at macro-expansion time — the derive emits a chained call on the model’s Fields struct (e.g. User::fields().comments().article()) and converts it into a stmt::Path, so a misspelled or otherwise unresolvable segment is a Rust compile error rather than a runtime schema validation failure.

Fields

path: Path

The resolved field path, rooted at the model that declares the via relation.
