From e4c8d0eb8ef4acb5d7a4252b3b87feb391ef7e41 Mon Sep 17 00:00:00 2001 From: Abseil Team Date: Fri, 18 Oct 2019 09:06:29 -0700 Subject: Export of internal Abseil changes -- a9ac6567c0933d786d68c10011e3f3ff9deedf89 by Greg Falcon : Add absl::FunctionRef, a type analogous to the proposed C++23 std::function_ref. Like std::function, FunctionRef can be used to type-erase any callable (invokable) object. However, FunctionRef works by reference: it does not store a copy of the type-erased object. If the wrapped object is destroyed before the FunctionRef, the reference becomes dangling. FunctionRef relates to std::function in much the same way that string_view relates to std::string. Because of these limitations, FunctionRef is best used only as a function argument type, and only where the function will be invoked immediately (rather than saved for later use). When `const std::function<...>&` is used in this way, `absl::FunctionRef<...>` is a better-performing replacement.

PiperOrigin-RevId: 275420901 -- 08d48ac004eba57cf2f1ada827181a2995f74807 by Abseil Team : Avoid applying the workaround for MSVC's static initialization problems when using clang-cl. PiperOrigin-RevId: 275366326 -- 40be82bd2b34670b5458c0a72a0475086153c2d6 by Abseil Team : Added comments to SimpleAtof()/SimpleAtod() that clarify that they always use the "C" locale, unlike the standard functions strtod() and strtof() referenced now in the comments. PiperOrigin-RevId: 275355815 -- 086779dacb3f6f2b3ab59947e94e79046bdb1fe1 by Jorg Brown : Move the hex conversion table used by escaping.cc into numbers.h so that other parts of Abseil can more efficiently access it.
