Struct pliantdb_core::connection::View[−][src]

pub struct View<'a, Cn, V: View> {
    pub key: Option<QueryKey<V::Key>>,
    pub access_policy: AccessPolicy,
    // some fields omitted
}

Parameters to query a schema::View.

Fields

key: Option<QueryKey<V::Key>>

Key filtering criteria.

access_policy: AccessPolicy
