UV - Perl interface to libuv
#!/usr/bin/env perl

use UV;
# hi-resolution time
my $hi_res_time = UV::hrtime();
# A new loop
my $loop = UV::Loop->new();
# default loop
my $loop = UV::Loop->default_loop(); # convenience constructor
my $loop = UV::Loop->new(1); # Tell the constructor you want the default loop
# run a loop with one of three options:
# UV_RUN_DEFAULT, UV_RUN_ONCE, UV_RUN_NOWAIT
$loop->run(); # runs with UV_RUN_DEFAULT
$loop->run(UV::Loop::UV_RUN_DEFAULT); # explicitly state UV_RUN_DEFAULT
$loop->run(UV::Loop::UV_RUN_ONCE);
$loop->run(UV::Loop::UV_RUN_NOWAIT);
This module provides an interface to libuv. We will try to document things here as best as we can, but we also suggest you look at the libuv docs directly for more details on how things work.
Event loops that work properly on all platforms. YAY!

The following functions are available:
my $loop = UV::default_loop();
# You can also get it with the UV::Loop methods below:
my $loop = UV::Loop->default_loop();
my $loop = UV::Loop->default();
# Passing a true value as the first arg to the UV::Loop constructor
# will also return the default loop
my $loop = UV::Loop->new(1);
Returns the default loop (which is a singleton object). This module already creates the default loop and you get access to it with this method.
my $uint64_t = UV::hrtime();
Get the current Hi-Res time (uint64_t).
