Struct CompletionSpanBuilder 

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

Builder for a canonical GenAI completion span.

Runtime spans declaring COMPLETION_PARENT_MARKER_FIELD and the COMPLETION_PARENT_REQUIRED_FIELDS are enriched and reused so one model turn has exactly one model span. Other ambient spans — and marker spans that omit a required field — remain parents of a newly created rig::completions span.

Implementations

impl<'a> CompletionSpanBuilder<'a>

pub fn new( provider: &'a str, request_model: &'a str, operation: CompletionOperation, ) -> Self

Create a completion-span builder for a provider request.

pub fn system_instructions( self, system_instructions: Option<&'a str>, record_content: bool, ) -> Self

Set the system instructions sent with the request when sensitive content telemetry has been explicitly enabled.

pub fn build(self) -> Span

Build a canonical completion span or enrich Rig’s current completion-parent span.
