Struct Span 

pub struct Span<'a> { /* private fields */ }

A live span within a trace.

When end() is called, the span data is pushed into the parent trace’s span list. The span uses a reference to the trace for this purpose.

Implementations

impl<'a> Span<'a>

pub fn new( trace: &'a Trace, span_type: SpanType, name: impl Into<String>, ) -> Self

Create a new span attached to the given trace.

pub fn model(self, model: impl Into<String>) -> Self

pub fn provider(self, provider: impl Into<String>) -> Self

pub fn input_text(self, input: impl Into<String>) -> Self

pub fn parent(self, parent_id: impl Into<String>) -> Self

pub fn set_tokens(&mut self, input: i64, output: i64)

pub fn set_cost(&mut self, cost: f64)

pub fn set_latency(&mut self, ms: i64)

pub fn set_output(&mut self, output: impl Into<String>)

pub fn set_error(&mut self, message: impl Into<String>)

pub fn set_time_to_first_token(&mut self, ms: i64)

pub fn end(self)

End the span and add it to the parent trace. If latency_ms was not set manually, it is computed from the start time.

pub fn data(&self) -> &SpanData

Borrow the underlying span data (read-only).
