NAME
OpenTelemetry::Propagator::TraceContext::TraceFlags - Represents TraceFlags in a W3C TraceContext
SYNOPSIS
use OpenTelemetry::Propagator::TraceContext::TraceFlags;
$off = OpenTelemetry::Propagator::TraceContext::TraceFlags->new;
say 'Not sampled' unless $off->sampled;
$on = OpenTelemetry::Propagator::TraceContext::TraceFlags->new(1);
say 'Sampled' if $on->sampled;DESCRIPTION
This class can be used to represent the trace flags as defined in a W3C TraceContext. Currently, this implements version 00 of that standard, so the only flag that is defined is the "sampled" flag.
METHODS
new
$traceflags = OpenTelemetry::Propagator::TraceContext::TraceFlags->new(
$numeric_value // 0,
);Takes a positional numeric value to use as the starting value for the flags. The value must be a positive integer less than or equal to 255. If the value is not, a warning will be logged and the value will be discarded.
If no value is given (or if the value given is undefined), the value will be set to a default of 0, meaning all flags are disabled.
flags
$numeric = $traceflags->flags;Returns the flags as a plan numeric scalar.
sampled
$bool = $traceflags->sampled;Returns true if the sampled flag is enabled, or false otherwise.
to_string
$string = $traceflags->to_string;Returns the flags stringified as a lowecase hexadecimal string.
