=head1 NAME
Test2::Util::Trace - Debug information for events
=head1 EXPERIMENTAL RELEASE
This is an experimental release. Using this right now is not recommended.
=head1 DESCRIPTION
The L<Test2::API::Context> object, as well as all L<Test2::Event> types need to
have access to information about where they were created. This object
represents that information.
=head1 SYNOPSIS
use Test2::Util::Trace;
my $trace = Test2::Util::Trace->new(
frame => [$package, $file, $line, $subname],
);
=head1 METHODS
=over 4
=item $trace->set_detail($msg)
=item $msg = $trace->detail
Used to get/set a custom trace message that will be used INSTEAD of
C<< at <FILE> line <LINE> >> when calling C<< $trace->debug >>.
=item $str = $trace->debug
Typically returns the string C<< at <FILE> line <LINE> >>. If C<detail> is set
then its value wil be returned instead.
=item $trace->alert($MESSAGE)
This issues a warning at the frame (filename and line number where
errors should be reported).
=item $trace->throw($MESSAGE)
This throws an exception at the frame (filename and line number where
errors should be reported).
=item $frame = $trace->frame()
Get the call frame arrayref.
=item ($package, $file, $line, $subname) = $trace->call()
Get the caller details for the debug-info. This is where errors should be
reported.
=item $pkg = $trace->package
Get the debug-info package.
=item $file = $trace->file
Get the debug-info filename.
=item $line = $trace->line
Get the debug-info line number.
=item $subname = $trace->subname
Get the debug-info subroutine name.
