Functions
new() → unix.seqpacket.acceptor
new() (1)
new(fd: file_descriptor) (2)
1 | Default constructor. |
2 | Converts a file descriptor into an unix.seqpacket.acceptor object. |
set_option(self, opt: string, val)
Set an option on the acceptor.
Currently available options are:
"enable_connection_aborted"
"debug"
get_option(self, opt: string) → value
Get an option from the acceptor.
Currently available options are:
"enable_connection_aborted"
"debug"
listen(self [, backlog: integer])
Place the acceptor into the state where it will listen for new connections.
backlog
is the maximum length of the queue of pending connections. If not
provided, an implementation defined maximum length will be used.
accept(self) → unix.seqpacket.socket
Initiate an accept operation and blocks current fiber until it completes or errs.
wait(self, wait_type: "read"|"write"|"error")
Wait for the socket to become ready to read, ready to write, or to have pending error conditions.
In short, the reactor model is exposed on top of the proactor model.
You shouldn’t be using reactor-style operations on Emilua. However if you’re trying to compete against systemD (or just xinetd) implementing a service manager employing socket activation then you’ll need the readiness event to trigger the managed service startup sequence. |
wait_type
can be one of the following:
"read"
-
Wait for a socket to become ready to read.
"write"
-
Wait for a socket to become ready to write.
"error"
-
Wait for a socket to have error conditions pending.
close(self)
Close the acceptor.
Forward the call to the function with same name in Boost.Asio:
Any asynchronous accept operations will be cancelled immediately.
A subsequent call to open() is required before the acceptor can again be used to again perform socket accept operations.
cancel(self)
Cancel all asynchronous operations associated with the acceptor.
Forward the call to the function with same name in Boost.Asio:
This function causes all outstanding asynchronous connect, send and receive operations to finish immediately, and the handlers for cancelled operations will be passed the
boost::asio::error::operation_aborted
error.
release(self) → file_descriptor
Release ownership of the native descriptor implementation.
Forward the call to the function with same name in Boost.Asio:
This function causes all outstanding asynchronous accept operations to finish immediately, and the handlers for cancelled operations will be passed the
boost::asio::error::operation_aborted
error. Ownership of the native acceptor is then transferred to the caller.
