10-- A socket is a handle to a protocol endpoint.
11--
12-- This module provides APIs to read and write streams and arrays from and to
13-- network sockets. Sockets may be connected or unconnected. Connected sockets
14-- can only send or recv data to/from the connected endpoint, therefore, APIs
15-- for connected sockets do not need to explicitly specify the remote endpoint.
16-- APIs for unconnected sockets need to explicitly specify the remote endpoint.

20-- Read IO requests to connected stream sockets are performed in chunks of
21-- 'Streamly.Internal.Memory.Array.Types.defaultChunkSize'. Unless specified
22-- otherwise in the API, writes are collected into chunks of
23-- 'Streamly.Internal.Memory.Array.Types.defaultChunkSize' before they are
24-- written to the socket. APIs are provided to control the chunking behavior.

28-- For additional, experimental APIs take a look at
29-- "Streamly.Internal.Network.Socket" module.
31-- By design, connected socket IO APIs are similar to
32-- "Streamly.Memory.Array" read write APIs. They are almost identical to the
33-- sequential streaming APIs in "Streamly.Internal.FileSystem.File".
