type ConfMultiError 

type ConfMultiError []error

ConfMultiError is an error wrapping multiple validation errors returned by Conf.ValidateAll() if the designated constraints aren't met.

func (ConfMultiError) AllErrors 

func (m ConfMultiError) AllErrors() []error

AllErrors returns a list of validation violation errors.

func (ConfMultiError) Error 

func (m ConfMultiError) Error() string

Error returns a concatenation of all the error messages it wraps.

type ConfValidationError 

type ConfValidationError struct {
	// contains filtered or unexported fields
}

ConfValidationError is the validation error returned by Conf.Validate if the designated constraints aren't met.

func (ConfValidationError) Cause 

func (e ConfValidationError) Cause() error

Cause function returns cause value.

func (ConfValidationError) Error 

func (e ConfValidationError) Error() string

Error satisfies the builtin error interface

func (ConfValidationError) ErrorName 

func (e ConfValidationError) ErrorName() string

type Metadata struct{}

Metadata is otel metadata propagator

func (Metadata) Extract 

func (b Metadata) Extract(parent context.Context, carrier propagation.TextMapCarrier) context.Context

Extract returns a copy of parent with the metadata from the carrier added.

func (Metadata) Fields 

func (b Metadata) Fields() []string

Fields returns the keys who's values are set with Inject.

func (Metadata) Inject 

func (b Metadata) Inject(ctx context.Context, carrier propagation.TextMapCarrier)

Inject sets metadata key-values from ctx into the carrier.

type TraceContext 

type TraceContext struct{}

TraceContext is a propagator that supports the W3C Trace Context format (https://www.w3.org/TR/trace-context/)

This propagator will propagate the traceparent and tracestate headers to guarantee traces are not broken. It is up to the users of this propagator to choose if they want to participate in a trace by modifying the traceparent header and relevant parts of the tracestate header containing their proprietary information.

func (TraceContext) Extract 

func (tc TraceContext) Extract(ctx context.Context, carrier propagation.TextMapCarrier) context.Context

Extract reads tracecontext from the carrier into a returned Context.

The returned Context will be a copy of ctx and contain the extracted tracecontext as the remote SpanContext. If the extracted tracecontext is invalid, the passed ctx will be returned directly instead.

func (TraceContext) Fields
