config JSON_LIBRARY
	bool "Build JSON library"
	help
	  Build a minimal JSON parsing/encoding library. Used by sample
	  applications such as the NATS client.

config RING_BUFFER
	bool "Ring buffers"
	help
	  Enable usage of ring buffers. This is similar to kernel FIFOs but ring
	  buffers manage their own buffer memory and can store arbitrary data.
	  For optimal performance, use buffer sizes that are a power of 2.

config NOTIFY
	bool "Asynchronous Notifications"
	help
	  Use this API to support async transactions.

config BASE64
	bool "Base64 encoding and decoding"
	help
	  Enable base64 encoding and decoding functionality

config ONOFF
	bool "On-Off Manager"
	select NOTIFY
	help
	  An on-off manager supports an arbitrary number of clients of a
	  service which has a binary state.  Example applications are power
	  rails, clocks, and binary device power management.

config WINSTREAM
	bool "Lockless shared memory window byte stream"
	help
	  Winstream is a byte stream IPC for use in shared memory
	  "windows", generally for transmit to non-Zephyr contexts that
	  can't share Zephyr APIs or data structures.

if WINSTREAM
config WINSTREAM_STDLIB_MEMCOPY
	bool "Use standard memcpy() in winstream"
	help
	  The sys_winstream utility is sometimes used in early boot
	  environments before the standard library is usable.  By
	  default it uses a simple internal bytewise memcpy().  Set
	  this to use the one from the standard library.
endif

config UTF8
	bool "UTF-8 string operation supported"
	help
	  Enable the utf8 API. The API implements functions to specifically
	  handle UTF-8 encoded strings.
