Struct Link 

#[non_exhaustive]
pub struct Link {
    pub trace_id: String,
    pub span_id: String,
    pub type: Type,
    pub attributes: Option<Attributes>,
    /* private fields */
}

A pointer from the current span to another span in the same trace or in a different trace. For example, this can be used in batching operations, where a single batch handler processes multiple requests from different traces or when the handler receives a request from a different project.

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.

trace_id: String

The [TRACE_ID] for a trace within a project.

span_id: String

The [SPAN_ID] for a span within a trace.

type: Type

The relationship of the current span relative to the linked span.

attributes: Option<Attributes>

A set of attributes on the link. Up to 32 attributes can be specified per link.

Implementations

impl Link

pub fn new() -> Self

pub fn set_trace_id<T: Into<String>>(self, v: T) -> Self

Sets the value of trace_id.

pub fn set_span_id<T: Into<String>>(self, v: T) -> Self

Sets the value of span_id.

pub fn set_type<T: Into<Type>>(self, v: T) -> Self

Sets the value of r#type.

pub fn set_attributes<T>(self, v: T) -> Self

where T: Into<Attributes>,

Sets the value of attributes.

pub fn set_or_clear_attributes<T>(self, v: Option<T>) -> Self

where T: Into<Attributes>,

Sets or clears the value of attributes.

Trait Implementations

impl Clone for Link

fn clone(&self) -> Link

Returns a duplicate 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 Default for Link

fn default() -> Link

Returns the “default value” for a type.

impl Message for Link

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Link

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