Enum ExpectedAncestry

pub enum ExpectedAncestry {
    HasExplicitParent(ExpectedSpan),
    IsExplicitRoot,
    HasContextualParent(ExpectedSpan),
    IsContextualRoot,
}

The ancestry of an event or span.

An event or span can have an explicitly assigned parent, or be an explicit root. Otherwise, an event or span may have a contextually assigned parent or in the final case will be a contextual root.

Variants

HasExplicitParent(ExpectedSpan)

The event or span has an explicitly assigned parent (created with parent: span_id) span.

IsExplicitRoot

The event or span is an explicitly defined root. It was created with parent: None and has no parent.

HasContextualParent(ExpectedSpan)

The event or span has a contextually assigned parent span. It has no explicitly assigned parent span, nor has it been explicitly defined as a root (it was created without the parent: directive). There was a span in context when this event or span was created.

IsContextualRoot

The event or span is a contextual root. It has no explicitly assigned parent, nor has it been explicitly defined as a root (it was created without the parent: directive). Additionally, no span was in context when this event or span was created.

Trait Implementations

impl Debug for ExpectedAncestry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ExpectedAncestry

fn eq(&self, other: &ExpectedAncestry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
