Fields

service: String

service is the name of the service with which this span is associated. @gotags: json:“service” msg:“service”

name: String

name is the operation name of this span. @gotags: json:“name” msg:“name”

resource: String

resource is the resource name of this span, also sometimes called the endpoint (for web spans). @gotags: json:“resource” msg:“resource”

trace_id: u64

traceID is the ID of the trace to which this span belongs. @gotags: json:“trace_id” msg:“trace_id”

span_id: u64

spanID is the ID of this span. @gotags: json:“span_id” msg:“span_id”

parent_id: u64

parentID is the ID of this span’s parent, or zero if this span has no parent. @gotags: json:“parent_id” msg:“parent_id”

start: i64

start is the number of nanoseconds between the Unix epoch and the beginning of this span. @gotags: json:“start” msg:“start”

duration: i64

duration is the time length of this span in nanoseconds. @gotags: json:“duration” msg:“duration”

error: i32

error is 1 if there is an error associated with this span, or 0 if there is not. @gotags: json:“error” msg:“error”

meta: HashMap<String, String>

meta is a mapping from tag name to tag value for string-valued tags. @gotags: json:“meta,omitempty” msg:“meta,omitempty”

metrics: HashMap<String, f64>

metrics is a mapping from tag name to tag value for numeric-valued tags. @gotags: json:“metrics,omitempty” msg:“metrics,omitempty”

type: String

type is the type of the service with which this span is associated. Example values: web, db, lambda. @gotags: json:“type” msg:“type”

meta_struct: HashMap<String, Vec<u8>>

meta_struct is a registry of structured “other” data used by, e.g., AppSec. @gotags: json:“meta_struct,omitempty” msg:“meta_struct,omitempty”

span_links: Vec<SpanLink>

span_links represents a collection of links, where each link defines a causal relationship between two spans. @gotags: json:“span_links,omitempty” msg:“span_links,omitempty”

span_events: Vec<SpanEvent>

spanEvents represent an event at an instant in time related to this span, but not necessarily during the span. @gotags: json:“span_events,omitempty” msg:“span_events,omitempty”

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl Default for Span

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Span

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for Span

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Span

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

impl Serialize for Span

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
