Test2::Util::Trace \- Debug information for events

The Test2::API::Context object, as well as all Test2::Event types need to
have access to information about where they were created.  This object
represents that information.

Used to get/set a custom trace message that will be used \s-1INSTEAD\s0 of
\&\f(CW\*(C`at <FILE> line <LINE>\*(C'\fR when calling \f(CW\*(C`$trace\->debug\*(C'\fR.
.ie n .IP "$str = $trace\->debug" 4
.el .IP "\f(CW$str\fR = \f(CW$trace\fR\->debug" 4
.IX Item "$str = $trace->debug"
Typically returns the string \f(CW\*(C`at <FILE> line <LINE>\*(C'\fR. If \f(CW\*(C`detail\*(C'\fR is set
then its value will be returned instead.
.ie n .IP "$trace\->alert($MESSAGE)" 4
.el .IP "\f(CW$trace\fR\->alert($MESSAGE)" 4
.IX Item "$trace->alert($MESSAGE)"
This issues a warning at the frame (filename and line number where
errors should be reported).
.ie n .IP "$trace\->throw($MESSAGE)" 4
.el .IP "\f(CW$trace\fR\->throw($MESSAGE)" 4
.IX Item "$trace->throw($MESSAGE)"
This throws an exception at the frame (filename and line number where
errors should be reported).

.el .IP "\f(CW$frame\fR = \f(CW$trace\fR\->\fIframe()\fR" 4

.IX Item "($package, $file, $line, $subname) = $trace->call()"
Get the caller details for the debug-info. This is where errors should be
reported.
.ie n .IP "$pkg = $trace\->package" 4
.el .IP "\f(CW$pkg\fR = \f(CW$trace\fR\->package" 4
.IX Item "$pkg = $trace->package"
Get the debug-info package.
.ie n .IP "$file = $trace\->file" 4
.el .IP "\f(CW$file\fR = \f(CW$trace\fR\->file" 4
.IX Item "$file = $trace->file"
Get the debug-info filename.
.ie n .IP "$line = $trace\->line" 4
.el .IP "\f(CW$line\fR = \f(CW$trace\fR\->line" 4
.IX Item "$line = $trace->line"
Get the debug-info line number.
