// This header file defines the `absl::optional` type for holding a value which
2017-09-19 22:54:40 +02:00
// may or may not be present. This type is useful for providing value semantics
// for operations that may either wish to return or hold "something-or-nothing".
//
// Example:
//
// // A common way to signal operation failure is to provide an output
// // parameter and a bool return type:
// bool AcquireResource(const Input&, Resource * out);
//
// // Providing an absl::optional return type provides a cleaner API:
// absl::optional<Resource> AcquireResource(const Input&);
//
// `absl::optional` is a C++11 compatible version of the C++17 `std::optional`
// abstraction and is designed to be a drop-in replacement for code compliant
// with C++17.

This is a forward-compatible implementation of std::from_chars from C++17. This provides exact "round_to_nearest" conversions, and has some nice properties: * Works with string_view (it can convert numbers from non-NUL-terminated buffers) * Never allocates memory * Faster than the standard library strtod() in our toolchain * Uses integer math in its calculations, so is unaffected by floating point environment * Unaffected by C locale Also change SimpleAtod/SimpleAtoi to use this new API under the hood.

// A value of type `absl::optional<T>` holds either a value of `T` or an
// "empty" value. When it holds a value of `T`, it stores it as a direct
// sub-object, so `sizeof(optional<T>)` is approximately
// `sizeof(T) + sizeof(bool)`.
//
// This implementation is based on the specification in the latest draft of the
// C++17 `std::optional` specification as of May 2017, section 20.6.
//
// Differences between `absl::optional<T>` and `std::optional<T>` include:
//
// * `constexpr` is not used for non-const member functions.
// (dependency on some differences between C++11 and C++14.)
// * `absl::nullopt` and `absl::in_place` are not declared `constexpr`. We
// need the inline variable support in C++17 for external linkage.
// * Throws `absl::bad_optional_access` instead of
// `std::bad_optional_access`.
// * `optional::swap()` and `absl::swap()` relies on
// `std::is_(nothrow_)swappable()`, which has been introduced in C++17.
// As a workaround, we assume `is_swappable()` is always `true`
// and `is_nothrow_swappable()` is the same as `std::is_trivial()`.
// * `make_optional()` cannot be declared `constexpr` due to the absence of
// guaranteed copy elision.
// * The move constructor's `noexcept` specification is stronger, i.e. if the
// default allocator is non-throwing (via setting
// `ABSL_ALLOCATOR_NOTHROW`), it evaluates to `noexcept(true)`, because
// we assume
// a) move constructors should only throw due to allocation failure and
// b) if T's move constructor allocates, it uses the same allocation
// function as the default allocator.
