From a00bdd176d66ef0b417d9576052a19091fbdf891 Mon Sep 17 00:00:00 2001 From: Abseil Team Date: Fri, 12 Oct 2018 06:53:34 -0700 Subject: Export of internal Abseil changes. -- fa894a667a3bebbe479539c8d5e829beebf36c27 by Abseil Team : Import of CCTZ from GitHub. PiperOrigin-RevId: 216855907 -- 59e0a42fa9045eb164573b82ce625248bd9999f3 by Jon Cohen : Some edits to the documentation for absl::Hash as I was reading through it. Itemized changes: * implement -> implements for grammar * Fix an incomplete sentence * specify *any* type T as opposed to *a* type T ? this is just the language I tend to see for these sorts of concepts in math and makes it more clear that we?re talking about a set of all types T satisfying these constraints * add arguments to comine() and combine_contiguous() ? this was mostly because for hash_continuous there was a reference to `size` elements without any mention of what `size` was.
