FunctionCallable

@dynamicCallable
public struct FunctionCallable : Sendable

为用户函数启用以下语法糖的结构：

guard case let .int32(sum) = try await user.functions.sum([1, 2, 3, 4, 5]) else {
   return
}

动态成员名称（上例中为sum ）由与函数名称直接关联的@dynamicMemberLookup提供。

  • 允许Future<AnyBSON, Error>可调用返回的 @DynamicCallable 实现。

    let cancellable = user.functions.sum(1, 2, 3, 4, 5)
   .sink(receiveCompletion: { result in
}, receiveValue: { value in
   // Returned value from function
})

  • dynamicallyCall(withArguments:) 异步(Asynchronous)

    允许async await可调用返回的 @DynamicMemberLookup 的实施。

    guard case let .int32(sum) = try await user.functions.sum(1, 2, 3, 4, 5) else {
   return
}
