For example, this change allows tests to use `EXPECT_THAT(cord.Chunks(), ElementsAre(...))` PiperOrigin-RevId: 406941278 -- 0c195f073632e21d9a4bce158047b2ba8551c2d1 by Evan Brown <ezb@google.com>: Use explicit exponential growth in SubstituteAndAppendArray.

PiperOrigin-RevId: 406891665 -- c9cff43d4c0568ed01f2fca0f6ef038ae03112b5 by Martijn Vels <mvels@google.com>: Add 'Rebuild' logic to CordRepBtree There are btree hostile scenarios where an application could perform repeated split/insert/merge operations on a cord leading to a tree exceeding the maximum height. While this should be rare in practice, this change adds a Rebuild() method that will rebuild a tree with a 100% fill factor, and we will invoke this rebuild when a tree exceeds the maximum height. This basically follows the similar 'balance' logic in Concat trees (although the latter is common in Concat uses) PiperOrigin-RevId: 406875739 -- 5b2b8fb88f1ebfdc1c670088152da2cb2ea4c376 by Martijn Vels <mvels@google.com>: Add 'in place' enabled RemoveSuffix An in-place RemoveSuffix is more efficient than SubTree() as it can directly modify privately owned nodes and flats allowing easy re-use of free capacity in right-most flats that may turn into Substring edges when using SubTree. PiperOrigin-RevId: 406431230 -- f09903c0a3d7344f59aaf1380a16ea10829217d4 by Derek Mauro <dmauro@google.com>: Internal change PiperOrigin-RevId: 406430373 -- 9957af575c33bb18dc170572a4ee8cc5901df6b2 by Greg Falcon <gfalcon@google.com>: Initial groundwork to allow storing checksum data inside CordRep instances. This uses a RefcountAndFlags bit that was reserved for this purpose, and will be leveraged in a follow-up change to allow attaching checksums to a Cord's value. This change splits RefcountAndFlags::IsOne() into two distinct operations: * IsOne(): This returns true when the associated CordRep is not shared with other threads. This is useful for functions that consume CordRep instances; for example, code that consumes an unshared CordRep can assume ownership of its children without modifying those refcounts. * IsMutable(): This returns true when the associated CordRep reference is not shared with other threads, *and* does not store an associated checksum value. This is useful for functions that modify a CordRep's contents: code may modify the bytes of a mutable-unshared CordRep without fear of races with other threads, or of invalidating a stored checksum. The tricky part of this CL is ensuring that the correct choice between IsMutable() and IsOne() was made at each point. An incorrect application of IsOne() could lead to correctness bugs in the future. Code conditioned on IsOne() may delete the CordRep in question, or assume ownership of its children, but must not modify the CordRep's data without explicitly adjusting the CRC.

PiperOrigin-RevId: 285220804 -- 68b015491f0dbf1ab547994673281abd1f34cd4b by Gennadiy Rozental <rogeeff@google.com>: This CL introduces following changes to the class FlagImpl: * We eliminate the CommandLineFlagLocks struct. Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately. * CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now. * Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call. * We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced.

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.
