[swift-evolution] Pitch: Deinit for structs

Introduction: This is a rather simple proposal, requesting that structs allow the ‘deinit’ destructor, as classes currently do. Motivation: Sometimes it is necessary to create an object that wraps a network connection (that needs to be closed when the object is destroyed), or that writes to a

Re: [swift-evolution] Pitch: Deinit for structs

Just chiming in with you two: deinit for a struct doesn't really work because structs are copied and destroyed all the time. Putting a file descriptor in a struct (along with destruction logic) would fail pretty hard without C++-like copy/move semantics. Félix > Le 23 déc. 2015 à 16:21:42,

Re: [swift-evolution] Pitch: Deinit for structs

This is something I asked for before, then I realized it wouldn’t work. func helper(rs: ResourceHandle) {} let resource = ResourceHandle() helper(resource) result.doSomething() // error Another example: let x = Handle() do { let y = x } // resources are freed here as deinit is called // x
