	Source string description type: paragraph

	English If a Secure WebSockets stream is desired, this is accomplished simply by changing the type of the next layer and adjusting the constructor arguments to match: 158/10000 · 158
5 string ID 37
	Source string description type: paragraph

	English Higher level abstractions can be developed in this fashion by nesting stream layers to arbitrary degree. The stack of stream layers effectively forms a compile-time singly linked list. The object at the end of this list is called the ['lowest layer], and is special from the others because it typically represents the underlying socket. 336/10000 · 336

11 string ID 46
	Source string description type: table cell

	English This stream can be used for synchronous and asynchronous reading and writing. It allows timeouts to be set on logical operations, and can have an executor associated with the stream which is used to invoke completion handlers. This lets you set a strand on the stream once, which is then used for all asynchronous operations automatically. 339/10000 · 339

	English This function closes a socket by performing an unqualified call to the [link beast.ref.boost__beast__beast_close_socket `beast_close_socket`] customization point, allowing sockets to be closed in generic contexts in an extensible fashion. 238/10000 · 238

17 string ID 46
	Source string description type: table cell

	English Returns the lowest layer in a stack of stream layers by recursively calling the `next_layer` member function on each object until reaching an object which lacks the member. This example puts a layered stream into non-blocking mode by retrieving the TCP/IP socket in the lowest layer and changing the socket option: [code_core_4_layers_4] 338/10000 · 338
