+ * AImageReader constructor similar to {@link AImageReader_newWithUsage} that takes

+ * and the return values are identical to those passed to {@link AImageReader_newWithUsage}.

+ * the combination of {@code hardwareBufferFormat} and {@code dataSpace} for the

+ *
+ * Available since API level 33.
+ *
+ * @param width The default width in pixels of the Images that this reader will produce.
+ * @param height The default height in pixels of the Images that this reader will produce.
+ * @param usage specifies how the consumer will access the AImage.
+ *              See {@link AImageReader_newWithUsage} parameter description for more details.
+ * @param maxImages The maximum number of images the user will want to access simultaneously.
+ *                  See {@link AImageReader_newWithUsage} parameter description for more details.
+ * @param hardwareBufferFormat The hardware buffer format passed by the producer.
+ *                             This must be one of the AHARDWAREBUFFER_FORMAT_* enum values defined
+ *                             in {@link hardware_buffer.h}.
+ * @param dataSpace The dataspace of the Image passed by the producer.
+ *                  This must be one of the ADATASPACE_* enum values defined in
+ *                  {@link ADataSpace}.
+ * @param reader The created image reader will be filled here if the method call succeeds.
+ *
+ * @return <ul>
+ *         <li>{@link AMEDIA_OK} if the method call succeeds.</li>
+ *         <li>{@link AMEDIA_ERROR_INVALID_PARAMETER} if reader is NULL, or one or more of width,

+ * FixedString is a stack allocatable string buffer that supports
+ * simple appending of other strings and string_views.
+ *
+ * It is designed for no-malloc operation when std::string
+ * small buffer optimization is insufficient.
+ *
+ * To keep code small, use asStringView() for operations on this.
+ *
+ * Notes:
+ * 1) Appending beyond the internal buffer size results in truncation.
+ *
+ * Alternatives:
+ * 1) If you want a sharable copy-on-write string implementation,
+ *    consider using the legacy android::String8().
+ * 2) Using std::string with a fixed stack allocator may suit your needs,
+ *    but exception avoidance is tricky.
+ * 3) Using C++20 ranges https://en.cppreference.com/w/cpp/ranges if you don't
+ *    need backing store.  Be careful about allocation with ranges.
+ *
+ * Good small sizes are multiples of 16 minus 2, e.g. 14, 30, 46, 62.
+ *
+ * Implementation Notes:
+ * 1) No iterators or [] for FixedString - please convert to std::string_view.
+ * 2) For small N (e.g. less than 62), consider a change to always zero fill and
+ *    potentially prevent always zero terminating (if one only does append).
+ *
+ * Possible arguments to create/append:
+ * 1) A FixedString.
+ * 2) A single char.
+ * 3) A char * pointer.
+ * 4) A std::string.
+ * 5) A std::string_view (or something convertible to it).
+ *
+ * Example:
+ *
+ * FixedString s1(std::string("a"));    // ctor
+ * s1 << "bc" << 'd' << '\n';           // streaming append
+ * s1 += "hello";                       // += append
+ * ASSERT_EQ(s1, "abcd\nhello");

+//
+// Some notable differences are:
+// - operator() is not const (unlike std::function where the call operator is
+// const even if the erased type is not const callable). This retains const
+// correctness by default. A workaround is keeping InPlaceFunction mutable.
+// - Moving from an InPlaceFunction leaves the object in a valid state (operator
+// bool remains true), similar to std::optional/std::variant.
+// Calls to the object are still defined (and are equivalent
+// to calling the underlying type after it has been moved from). To opt-out
+// (and/or ensure safety), clearing the object is recommended:
+//      func1 = std::move(func2); // func2 still valid (and moved-from) after this line
+//      func2 = nullptr; // calling func2 will now abort
+// - Unsafe implicit conversions of the return value to a reference type are
+// prohibited due to the risk of dangling references (some of this safety was
+// added to std::function in c++23). Only converting a reference to a reference to base class is
+// permitted:
+//      std::function<Base&()> = []() -> Derived& {...}
+// - Some (current libc++ implementation) implementations of std::function
+// incorrectly fail to handle returning non-moveable types which is valid given
+// mandatory copy elision.
+//
+// Additionally, the stored functional will use the typical rules of overload
+// resolution to disambiguate the correct call, except, the target class will
+// always be implicitly a non-const lvalue when called. If a different overload
+// is preferred, wrapping the target class in a lambda with explicit casts is
+// recommended (or using inheritance, mixins or CRTP). This avoids the
+// complexity of utilizing abonimable function types as template params.
