View Source ThousandIsland.Socket (Thousand Island v1.0.0-pre.7)
Encapsulates a client connection's underlying socket, providing a facility to read, write, and otherwise manipulate a connection from a client.
Summary
Functions
Closes the given socket. Note that a socket is automatically closed when the handler process which owns it terminates
Gets the given flags on the socket
Returns statistics about the connection.
Handshakes the underlying socket if it is required (as in the case of SSL sockets, for example).
Returns information about the protocol negotiated during transport handshaking (if any).
Returns information in the form of t:public_key.der_encoded() about the peer certificate of the socket.
Returns information in the form of t:ThousandIsland.Transport.socket_info() about the remote end of the socket.
Returns available bytes on the given socket. Up to length bytes will be
returned (0 can be passed in to get the next 'available' bytes, typically the
next packet). If insufficient bytes are available, the function can wait timeout
milliseconds for data to arrive.
Returns whether or not this protocol is secure.
Sends the given data (specified as a binary or an IO list) on the given socket.
Sends the contents of the given file based on the provided offset & length
Sets the given flags on the socket
Shuts down the socket in the given direction.
Returns information in the form of t:ThousandIsland.Transport.socket_info() about the local end of the socket.
Returns the telemetry span representing the lifetime of this socket
Types
@type t() :: %ThousandIsland.Socket{ read_timeout: timeout(), socket: ThousandIsland.Transport.socket(), span: ThousandIsland.Telemetry.t(), transport_module: module() }
A reference to a socket along with metadata describing how to use it
Functions
@spec close(t()) :: ThousandIsland.Transport.on_close()
Closes the given socket. Note that a socket is automatically closed when the handler process which owns it terminates
@spec getopts(t(), ThousandIsland.Transport.socket_get_options()) :: ThousandIsland.Transport.on_getopts()
Gets the given flags on the socket
Errors are usually from :inet.posix(), however, SSL module defines return type as any()
@spec getstat(t()) :: ThousandIsland.Transport.socket_stats()
Returns statistics about the connection.
@spec handshake(t()) :: ThousandIsland.Transport.on_handshake()
Handshakes the underlying socket if it is required (as in the case of SSL sockets, for example).
This is normally called internally by ThousandIsland.Handler and does not need to be
called by implementations which are based on ThousandIsland.Handler
@spec negotiated_protocol(t()) :: ThousandIsland.Transport.on_negotiated_protocol()
Returns information about the protocol negotiated during transport handshaking (if any).
@spec peercert(t()) :: ThousandIsland.Transport.on_peercert()
Returns information in the form of t:public_key.der_encoded() about the peer certificate of the socket.
@spec peername(t()) :: ThousandIsland.Transport.on_peername()
Returns information in the form of t:ThousandIsland.Transport.socket_info() about the remote end of the socket.
@spec recv(t(), non_neg_integer(), timeout() | nil) :: ThousandIsland.Transport.on_recv()
Returns available bytes on the given socket. Up to length bytes will be
returned (0 can be passed in to get the next 'available' bytes, typically the
next packet). If insufficient bytes are available, the function can wait timeout
milliseconds for data to arrive.
Returns whether or not this protocol is secure.
@spec send(t(), iodata()) :: ThousandIsland.Transport.on_send()
Sends the given data (specified as a binary or an IO list) on the given socket.
@spec sendfile(t(), String.t(), non_neg_integer(), non_neg_integer()) :: ThousandIsland.Transport.on_sendfile()
Sends the contents of the given file based on the provided offset & length
@spec setopts(t(), ThousandIsland.Transport.socket_set_options()) :: ThousandIsland.Transport.on_setopts()
Sets the given flags on the socket
Errors are usually from :inet.posix(), however, SSL module defines return type as any()
@spec shutdown(t(), ThousandIsland.Transport.way()) :: ThousandIsland.Transport.on_shutdown()
Shuts down the socket in the given direction.
@spec sockname(t()) :: ThousandIsland.Transport.on_sockname()
Returns information in the form of t:ThousandIsland.Transport.socket_info() about the local end of the socket.
@spec telemetry_span(t()) :: ThousandIsland.Telemetry.t()
Returns the telemetry span representing the lifetime of this socket
