-# libbase
-
-## Who is this library for?
-
-This library is a collection of convenience functions to make common tasks
-easier and less error-prone.
-
-In this context, "error-prone" covers both "hard to do correctly" and
-"hard to do with good performance", but as a general purpose library,
-libbase's primary focus is on making it easier to do things easily and
-correctly when a compromise has to be made between "simplest API" on the
-one hand and "fastest implementation" on the other. Though obviously
-the ideal is to have both.
-
-## Should my routine be added?
-
-The intention is to cover the 80% use cases, not be all things to all users.
-
-If you have a routine that's really useful in your project,
-congratulations. But that doesn't mean it should be here rather than
-just in your project.
-
-The question for libbase is "should everyone be doing this?"/"does this
-make everyone's code cleaner/safer?". Historically we've considered the
-bar for inclusion to be "are there at least three *unrelated* projects
-that would be cleaned up by doing so".
-
-If your routine is actually something from a future C++ standard (that
-isn't yet in libc++), or it's widely used in another library, that helps
-show that there's precedent. Being able to say "so-and-so has used this
-API for n years" is a good way to reduce concerns about API choices.
-
-## Any other restrictions?
-
-Unlike most Android code, code in libbase has to build for Mac and
-Windows too.
-
-Code here is also expected to have good test coverage.
-
-By its nature, it's difficult to change libbase API. It's often best
-to start using your routine just in your project, and let it "graduate"
-after you're certain that the API is solid.

-// Google-style C++ logging.

-//
-// LOG(INFO) << "Some text; " << some_value;
-//
-// Replace `INFO` with any severity from `enum LogSeverity`.
-//
-// To log the result of a failed function and include the string

-//

-// This file contains classes for returning a successful result along with an optional
-// arbitrarily typed return value or for returning a failure result along with an optional string
-// indicating why the function failed.
-
-// There are 3 classes that implement this functionality and one additional helper type.
-//
-// Result<T> either contains a member of type T that can be accessed using similar semantics as
-// std::optional<T> or it contains a ResultError describing an error, which can be accessed via
-// Result<T>::error().
-//
-// ResultError is a type that contains both a std::string describing the error and a copy of errno
-// from when the error occurred. ResultError can be used in an ostream directly to print its
-// string value.
-//
-// Result<void> is the correct return type for a function that either returns successfully or
-// returns an error value. Returning {} from a function that returns Result<void> is the
-// correct way to indicate that a function without a return type has completed successfully.
-//
-// A successful Result<T> is constructed implicitly from any type that can be implicitly converted
-// to T or from the constructor arguments for T. This allows you to return a type T directly from
-// a function that returns Result<T>.
-//
-// Error and ErrnoError are used to construct a Result<T> that has failed. The Error class takes
-// an ostream as an input and are implicitly cast to a Result<T> containing that failure.
-// ErrnoError() is a helper function to create an Error class that appends ": " + strerror(errno)
-// to the end of the failure string to aid in interacting with C APIs. Alternatively, an errno
-// value can be directly specified via the Error() constructor.
-//
-// Errorf and ErrnoErrorf accept the format string syntax of the fmblib (https://fmt.dev).
-// Errorf("{} errors", num) is equivalent to Error() << num << " errors".
-//
-// ResultError can be used in the ostream and when using Error/Errorf to construct a Result<T>.
-// In this case, the string that the ResultError takes is passed through the stream normally, but
-// the errno is passed to the Result<T>. This can be used to pass errno from a failing C function up
-// multiple callers. Note that when the outer Result<T> is created with ErrnoError/ErrnoErrorf then
-// the errno from the inner ResultError is not passed. Also when multiple ResultError objects are
-// used, the errno of the last one is respected.
-//
-// ResultError can also directly construct a Result<T>. This is particularly useful if you have a
-// function that return Result<T> but you have a Result<U> and want to return its error. In this
-// case, you can return the .error() from the Result<U> to construct the Result<T>.
-
-// An example of how to use these is below:
-// Result<U> CalculateResult(const T& input) {
-// U output;
-// if (!SomeOtherCppFunction(input, &output)) {
-// return Errorf("SomeOtherCppFunction {} failed", input);
-// }
-// if (!c_api_function(output)) {
-// return ErrnoErrorf("c_api_function {} failed", output);
-// }
-// return output;
-// }
-//
-// auto output = CalculateResult(input);
-// if (!output) return Error() << "CalculateResult failed: " << output.error();
-// UseOutput(*output);
