Struct opentelemetry_api::trace::Link

#[non_exhaustive]
pub struct Link {
    pub span_context: SpanContext,
    pub attributes: Vec<KeyValue>,
    pub dropped_attributes_count: u32,
}

Available on crate feature trace only.

Link is the relationship between two Spans.

The relationship can be within the same trace or across different traces.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

span_context: SpanContext

The span context of the linked span.

attributes: Vec<KeyValue>

Attributes that describe this link.

dropped_attributes_count: u32

The number of attributes that were above the configured limit, and thus dropped.

Implementations

impl Link

pub fn new(span_context: SpanContext, attributes: Vec<KeyValue>) -> Self

Create a new link.

Trait Implementations

impl Clone for Link

fn clone(&self) -> Link

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Link

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

Formats the value using the given formatter.

impl PartialEq<Link> for Link

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

This method tests for self and other values to be equal, and is used by ==.

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

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