struct RelationQuery

Bases:

• Sendable
• Hashable
• Decodable
• Encodable
• SendableMetatype
• Equatable

A quantified filter over a relation, as one value.

Pairing the quantifier with the expression is what lets a relation filter travel: "sessions where *some* pane runs nvim" is a single Codable thing a client can send, rather than two arguments a boundary has to reassemble.

Members

• !=(_:_:) function Returns a Boolean value indicating whether two values are not equal.
• init(_:_:) method
• init(from:) method Creates a new instance by decoding from the given decoder.
• expression property What each related object is tested against.
• quantifier property How many of the related objects have to match for the owner to be selected.
