NAME
OpenTelemetry::Propagator::TraceContext - Propagate context using the W3C TraceContext format
SYNOPSIS
use OpenTelemetry::Trace;
use OpenTelemetry::Propagator::TraceContext;
my $propagator = OpenTelemetry::Propagator::TraceContext;
# Inject TraceContext data from the context to a carrier
my $carrier = {};
$propagator->inject( $carrier, $context );
# Extract TraceContext data from a carrier to the context
my $new_context = $propagator->extract( $carrier, $context );
# The TraceContext data will be in the span in the context
my $span = OpenTelemetry::Trace->span_from_context($new_context);
DESCRIPTION
This package defines a propagator class that can interact with the context (which can be either an implicit or explicit instance of OpenTelemetry::Context) and inject or extract data using the W3C TraceContext format.
It implements the propagator interface defined in OpenTelemetry::Propagator.
METHODS
inject
$propagator = $propagator->inject(
$carrier,
$context // OpenTelemetry::Context->current,
$setter // OpenTelemetry::Propagator::TextMap::SETTER,
)
extract
$new_context = $propagator->extract(
$carrier,
$context // OpenTelemetry::Context->current,
$getter // OpenTelemetry::Propagator::TextMap::GETTER,
)
keys
@keys = $propagator->keys
