NAME

OpenTracing::Types - Type constraints for checking Interfaces

SYNOPSIS

    use OpenTracing::Types qw/Span/;
    #
    # imports the 'Span' Type
    
    use Types::Standard qw/Maybe/;
    use Types::Common::Numeric qw/PositiveOrZeroNum/;
    
    use Function::Parameters;
    use Function::Return;
    
    # create a subroutine with some fancy type checks
    #
    sub time_gap (Span $span1, Span $span2) :Return Maybe[PositiveOrZeroNum] {
        return unless $span1->finish_time and $span2->start_time;
        return $span2->start_time - $span1->finish_time
    }

DESCRIPTION

This library of Type::Tiny type constraints provide Duck Type checks for all common elements that conform OpenTracing::Interface

See "Export" in Type::Library about the various ways to import types an related methods.

TYPES

The following Duck Types are being defined with the mentioned required methods:

ContextReference

new_child_of
new_follows_from
get_referenced_context
type_is_child_of
type_is_follows_from

See also "INSTANCE METHODS" in OpenTracing::Interface::ContextReference and "CONSTRUCTOR METHODS" in OpenTracing::Interface::ContextReference.

Scope

close
get_span

See also "INSTANCE METHODS" in OpenTracing::Interface::Scope.

ScopeManager

activate_span
get_active_scope

See also "INSTANCE METHODS" in OpenTracing::Interface::ScopeManager.

Span

get_context
overwrite_operation_name
finish
set_tag
log_data
set_baggage_item
get_baggage_item

See also "INSTANCE METHODS" in OpenTracing::Interface::Span.

SpanContext

get_baggage_item
with_baggage_item

See also "INSTANCE METHODS" in OpenTracing::Interface::SpanContext.

Tracer

get_scope_manager
get_active_span
start_active_span
start_span
inject_context
extract_context
