* Revert "Revert count(where:)"
This reverts commit 779ea19a6a.
Now that SE-0220 has been re-accepted, this adds the `count(where:)`
Sequence method to the standard library.
* Revise the Unicode scalar/Character properties
* Minor revisions to `compactMapValues` docs.
* Add documentation for AdditiveArithmetic, revise Numeric
* Apply minor style updates to count(where:).
* Revise string interpolation docs.
- Convert table of interpolation examples to a list of examples. Tables
aren't supported by Swift markup, so this wouldn't render properly in
Xcode or on the web.
- Add a description of what a user must implement in a custom
string interpolation type to get the behavior they want.
* Revise isMultiple(of:) docs.
- In particular, add emphasis to mathematical symbols and equations to
match how we document such things elsewhere.
- I'm using asterisks for single symbols, and underscores for equations
because it's easier to read in-source when you don't have to escape
multiplication within emphasis.
* Add some abstracts to the SIMD vector types.
- Adds a dictionary of spelled out numbers. Only numbers < 10
should be spelled out according to editorial.
- Adds abstracts to some of the basic members.
- Includes parameter descriptions for the xyzw properties and inits,
but not for the unlabeled initializers. Combined with the protocol
extension method abstracts, this should complete coverage of the concrete
types.
* [stdlib] Minor documentation revisions
* [docs] Convert 'nonoptional' to 'non-optional'
We're switching to 'non-optional' across the board, as the unhyphenated
form is too easy to read as 'no-noptional'.
* add count(where:) and tests
* Revise count(where:) documentation
* Remove errant word in abstract
* add a benchmark for ranges and strings with help from @natecook1000
* update benchmark to use Array instead of Range
* [stdlib] Update complexity docs for seq/collection algorithms
This corrects and standardizes the complexity documentation for Sequence
and Collection methods. The use of constants is more consistent, with `n`
equal to the length of the target collection, `m` equal to the length of
a collection passed in as a parameter, and `k` equal to any other passed
or calculated constant.
* Apply notes from @brentdax about complexity nomenclature
* Change `n` to `distance` in `index(_:offsetBy:)`
* Use equivalency language more places; sync across array types
* Use k instead of n for parameter names
* Slight changes to index(_:offsetBy:) discussion.
* Update tests with new parameter names
- Revise Bool.toggle() discussion and fix attribute placement
- Revise to Hasher abstracts and discussions
- Correct the name of the remainder operator
- Clean up deprecations and paste-os w/in UnsafePointer
