slices: initial implementation of sorting functions Implements golang/go#47619 in the exp/slices package as a testing ground prior to inclusion in the standard library. Relies on the modified sorting function code generator proposed in https://go-review.googlesource.com/c/go/+/353069 to automatically generate the code of the sorting functions. Benchmark comparing sort.Ints with the generic Sort function added in this CL to sort a slice of int: name old time/op new time/op delta Sort-8 12.0ms ± 1% 6.5ms ± 1% -46.02% (p=0.000 n=9+10) Benchmark comparing sort.Sort with SortFunc to sort a slice of struct pointers based on one field in the struct: name old time/op new time/op delta SortStructs-8 18.6ms ± 2% 15.9ms ± 3% -14.43% (p=0.000 n=10+10) Change-Id: Ic301aae7e5b8f99144e39b8a77fde897779588ed Reviewed-on: https://go-review.googlesource.com/c/exp/+/378134 Reviewed-by: Ian Lance Taylor <iant@golang.org> Trust: Cody Oss <codyoss@google.com> Trust: Jeremy Faller <jeremy@golang.org>
This subrepository holds experimental and deprecated (in the old directory) packages.
The idea for this subrepository originated as the pkg/exp directory of the main repository, but its presence there made it unavailable to users of the binary downloads of the Go installation. The subrepository has therefore been created to make it possible to go get these packages.
Warning: Packages here are experimental and unreliable. Some may one day be promoted to the main repository or other subrepository, or they may be modified arbitrarily or even disappear altogether.
In short, code in this subrepository is not subject to the Go 1 compatibility promise. (No subrepo is, but the promise is even more likely to be violated by go.exp than the others.)
Caveat emptor.
