Introduce (recursive) constraints that make the *Collection constraint
of SubSequence match that of its enclosing *Collection, e.g.,
MutableCollection.SubSequence conforms to MutableCollection.
Fixes rdar://problem/20715031 and more of SR-3453.
* Unify the capitalization across all user-visible error messages (fatal errors, assertion failures, precondition failures) produced by the runtime, standard library and the compiler.
* Update some more tests to the new expectations.
This overload allows `String.filter` to return a `String`, and not
`[Character]`.
In the other hand, introduction of this overload makes `[123].filter`
somewhat ambiguous in a sence, that the compiler will now prefer an
implementatin from a more concrete protocol, which is less efficient for
arrays, therefore extra work is needed to make sure Array types fallback
to the `Sequence.filter`.
Implements: <rdar://problem/32209927>
* Give Sequence a top-level Element, constrain Iterator to match
* Remove many instances of Iterator.
* Fixed various hard-coded tests
* XFAIL a few tests that need further investigation
* Change assoc type for arrayLiteralConvertible
* Mop up remaining "better expressed as a where clause" warnings
* Fix UnicodeDecoders prototype test
* Fix UIntBuffer
* Fix hard-coded Element identifier in CSDiag
* Fix up more tests
* Account for flatMap changes
* One-sided ranges and RangeExpression
* Remove redundant ClosedRange methods from String
* Fix up brittle tests
* Account for Substring update
* XFAIL range diagnostics on Linux
These were overlooked, and somehow code that attempted to make a minimal collection conform to RangeReplaceableCollection and RandomAccessCollection managed to compile successfully in Swift 3.0, but in Swift 3.1…*something* changed to reject a type that conforms to both due to the lack of a suitable default slicing subscript implementation in the stdlib that provided all the requirements. Fill in these missing implementations, fixing rdar://problem/30228957.
It's important to let people know that, in contrast with existing
practice in other frameworks, we really are going to remove the
deprecated API, and soon.
Added tests for expected-error and fix-its.
- Add arguments signature regardless that is the same as before.
Because the error message looks more natural.
e.g. "makeIterator" => "makeIterator()",
"replaceSubrange" => "replaceSubrange(_:with:)"
- Any${ExistentialCollection}.underestimateCount() was a method, not
computed property.
- 'LazySequenceType' has been renamed to 'LazySequenceProtocol', but not
'LazyCollectionProtocol'
- Streamable.writeTo(_:) had no argument label.
- Fixed typo in print() debugPrint() error message (not working for now)
- Repeated.init(): changed `renamed` to `message` because the arugment
order has changed.
- Marked `public` for some unavailable method on `Sequence`
- Sequence.split(_:maxSplit:allowEmptySlices) was replaced with
split(separator:maxSplits:omittingEmptySubsequences:),
not split(separator:omittingEmptySubsequences:isSeparator:)
- Sequence.split(_:allowEmptySlices:isSeparator) was replaced with
split(maxSplits:omittingEmptySubsequences:isSeparator:),
not split(_:omittingEmptySubsequences:isSeparator:)
- Sequence.startsWith(_:isEquivalent:) or startsWith(_:) had no label on
the first argument.
- transcode(_:_:_:_:stopOnError), not transcode(_:_:_:_:stoppingOnError)
- Removed mutating methods from UnsafePointer.
alloc(_:), dealloc(_:), setter:memory, initialize(_:), destroy(),
and destroy(_:)
This revises and expands on documentation for the new collection methods
for working with indices and the revised Swift 3 set APIs. In addition,
it includes documentation for the new range types.
The RangeProtocol was a very weak and fragile abstraction because it
didn't specify the interpretation of the endpoints. To write a
non-trivial algorithm, one usually needed to consult that information.
The standard library code only actually worked correctly with half-open
and closed ranges (and didn't handle fully open ranges, for example).
The other two protocols, HalfOpenRangeProtocol and ClosedRangeProtocol,
were only used for code sharing, and present an ABI burden. We can use
gyb instead.
