Struct Span 

#[non_exhaustive]
pub struct Span {
    pub span_id: String,
    pub assistant_id: String,
    pub session_id: String,
    pub parent_span_id: Option<String>,
    pub span_name: String,
    pub span_type: SpanType,
    pub start_timestamp: DateTime,
    pub end_timestamp: DateTime,
    pub status: SpanStatus,
    pub request_id: String,
    pub attributes: Option<SpanAttributes>,
}

A span represents a unit of work during AI agent execution, capturing timing, status, and contextual attributes.

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_id: String

Unique span identifier

assistant_id: String

UUID of the Connect AI Assistant resource

session_id: String

UUID of the Connect AI Session resource

parent_span_id: Option<String>

Parent span identifier for hierarchy. Null for root spans.

span_name: String

Service-defined operation name

span_type: SpanType

Operation relationship type

start_timestamp: DateTime

Operation start time in milliseconds since epoch

end_timestamp: DateTime

Operation end time in milliseconds since epoch

status: SpanStatus

Span completion status

request_id: String

The service request ID that initiated the operation

attributes: Option<SpanAttributes>

Span-specific contextual attributes

Implementations

impl Span

pub fn span_id(&self) -> &str

Unique span identifier

pub fn assistant_id(&self) -> &str

UUID of the Connect AI Assistant resource

pub fn session_id(&self) -> &str

UUID of the Connect AI Session resource

pub fn parent_span_id(&self) -> Option<&str>

Parent span identifier for hierarchy. Null for root spans.

pub fn span_name(&self) -> &str

Service-defined operation name

pub fn span_type(&self) -> &SpanType

Operation relationship type

pub fn start_timestamp(&self) -> &DateTime

Operation start time in milliseconds since epoch

pub fn end_timestamp(&self) -> &DateTime

Operation end time in milliseconds since epoch

pub fn status(&self) -> &SpanStatus

Span completion status

pub fn request_id(&self) -> &str

The service request ID that initiated the operation

pub fn attributes(&self) -> Option<&SpanAttributes>

Span-specific contextual attributes

impl Span

pub fn builder() -> SpanBuilder

Creates a new builder-style object to manufacture Span.

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 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.
