Deferred

public struct Deferred<Value>

A value that may become determined (or filled) at some point in the future. Once determined, it cannot change.

You may subscribe to be notified once the value becomes determined.

Handlers and their captures are strongly referenced until:

  • they are executed when the value is determined
  • the last copy to this type escapes without the value becoming determined

If the value never becomes determined, a handler submitted to it will never be executed.
