Single frame of a Backtrace
class Backtrace::Frame { }
A single backtrace frame. It identifies a location in the source code.
method file(Backtrace::Frame:D --> Str)
Returns the file name.
my $bt = Backtrace.new;
my $btf = $bt[0];
say $btf.file;
method line(Backtrace::Frame:D --> Int)
Returns the line number (line numbers start counting from 1).
my $bt = Backtrace.new;
my $btf = $bt[0];
say $btf.line;
method code(Backtrace::Frame:D)
Returns the code object into which .file and .line point, if available.
my $bt = Backtrace.new;
my $btf = $bt[0];
say $btf.code;
method subname(Backtrace::Frame:D --> Str)
Returns the name of the enclosing subroutine.
my $bt = Backtrace.new;
my $btf = $bt[0];
say $btf.subname;
method is-hidden(Backtrace::Frame:D: --> Bool:D)
Returns True if the frame is marked as hidden with the is hidden-from-backtrace trait.
my $bt = Backtrace.new;
my $btf = $bt[0];
say $btf.is-hidden;
method is-routine(Backtrace::Frame:D: --> Bool:D)
Return True if the frame points into a routine (and not into a mere Block).
my $bt = Backtrace.new;
my $btf = $bt[0];
say $btf.is-routine;
method is-setting(Backtrace::Frame:D: --> Bool:D)
Returns True if the frame is part of a setting.
my $bt = Backtrace.new;
my $btf = $bt[0];
say $btf.is-setting; # OUTPUT: «True»
