NAME
Ryu::Async - use Ryu with IO::Async
SYNOPSIS
#!/usr/bin/env perl
use strict;
use warnings;
use IO::Async::Loop;
use Ryu::Async;
# This will generate a lot of output, but is useful
# for demonstrating lifecycles. Drop this to 'info' or
# 'debug' to make it more realistic.
use Log::Any::Adapter qw(Stdout), log_level => 'trace';
#
my $loop = IO::Async::Loop->new;
$loop->add(
my $ryu = Ryu::Async->new
);
{
my $timer = $ryu->timer(
interval => 0.10,
)->take(10)
->each(sub { print "tick\n" });
warn $timer->describe;
$timer->get;
}
DESCRIPTION
This is an IO::Async::Notifier subclass for interacting with Ryu.
METHODS
from
Creates a new Ryu::Source from a thing.
The exact details of this are likely to change in future, but a few
things that are expected to work:
$ryu->from($io_async_stream_instance)
->by_line
->each(sub { print "Line: $_\n" });
$ryu->from([1..1000])
->sum
->each(sub { print "Total was $_\n" });
from_stream
Create a new Ryu::Source from an IO::Async::Stream instance.
Note that a stream which is not already attached to an
IO::Async::Notifier will be added as a child of this instance.
stdin
Create a new Ryu::Source that wraps STDIN.
As with other IO::Async::Stream wrappers, this will emit data as soon
as it's available, as raw bytes.
Use "by_line" in Ryu::Source and "decode" in Ryu::Source to split into
lines and/or decode from UTF-8.
stdout
Returns a new Ryu::Sink that wraps STDOUT.
timer
Provides a Ryu::Source which emits an empty string at selected
intervals.
Takes the following named parameters:
* interval - how often to trigger the timer, in seconds (fractional
values allowed)
* reschedule - type of rescheduling to use, can be soft, hard or
drift as documented in IO::Async::Timer::Periodic
Example:
$ryu->timer(interval => 1, reschedule => 'hard')
->combine_latest(...)
run
Creates an IO::Async::Process.
source
Returns a new Ryu::Source instance.
udp_client
Creates a new UDP client.
This provides a sink for "outgoing" in Ryu::Async::Client packets, and
a source for "incoming" in Ryu::Async::Client responses.
* uri - an optional URI of the form udp://host:port
* host - which host to listen on, defaults to 0.0.0.0
* port - the port to listen on
Returns a Ryu::Async::Client instance.
udp_server
sink
Returns a new Ryu::Sink.
The label will default to the calling package/class and method, with
some truncation rules:
* A Net::Async:: prefix will be replaced by Na.
* A Web::Async:: prefix will be replaced by Wa.
* A IO::Async:: prefix will be replaced by Ia.
* A Tickit::Async:: prefix will be replaced by Ta.
* A Tickit::Widget:: prefix will be replaced by TW.
This list of truncations is subject to change, so please don't rely on
any of these in string matches or similar - better to set your own
label if you need consistency.
