Struct ViewDelegateNoUnique

Source

pub struct ViewDelegateNoUnique<'a, V: 'static> { /* private fields */ }

Expand description

View delegate for views declared @@no_unique. Exposes only find_many — find_unique and refresh() are absent at the type level because:

find_unique needs an @id field, which @@no_unique views opt out of (validator-enforced).
@@materialized + @@no_unique is a parse-time error (concurrent refresh requires a unique index), so a ViewDelegateNoUnique can never be materialized.

PK is fixed to () because the underlying ViewDescriptor<V, ()> stores an empty primary_key string — preventing any code path from constructing one with a real PK type.
