Re: [swift-evolution] [Review] SE-0191: Eliminate IndexDistance from Collection

Distance must be signed, so it cannot be UInt. On Wed, Nov 29, 2017 at 11:14 Wallacy wrote: > I think is that's why some folks ask for count be UInt (or UInt64 when > appropriate) some time ago. > > I dont know how solve this, but appear to be less painful than current >

Re: [swift-evolution] [Review] SE-0191: Eliminate IndexDistance from Collection

I think is that's why some folks ask for count be UInt (or UInt64 when appropriate) some time ago. I dont know how solve this, but appear to be less painful than current IndexDistance. Em qua, 29 de nov de 2017 às 14:46, Ben Cohen via swift-evolution < swift-evolution@swift.org> escreveu: > You

So that we are all clear on the implications of this, if IndexDistance becomes Int, ranges of integers will stop conforming to Collection, because Int.min.. wrote: > My suggestion would be: don’t have your Collection-like type conform to > Collection. Give it collection-like methods if you want

Re: [swift-evolution] [Review] SE-0191: Eliminate IndexDistance from Collection

My suggestion would be: don’t have your Collection-like type conform to Collection. Give it collection-like methods if you want them, like an indexing and slicing subscript that takes an Int64. It can still conform to Sequence. In practice, these “huge” collections will be mostly used

Re: [swift-evolution] [Review] SE-0191: Eliminate IndexDistance from Collection

The proposal mentions one reasonable situation where a larger-than-Int type would be useful, namely a Collection wrapping a memory-mapped file, being used on 32-bit systems. Is there a recommended migration strategy for this scenario? Nevin On Mon, Nov 27, 2017 at 8:34 PM, Douglas Gregor via
