Struct RunScope 

pub struct RunScope { /* private fields */ }

Ergonomic wrapper around Tracer that standardizes:

• inputs/outputs serialization
• post/end/patch flow
• error handling (best-effort patching)

This is intended to keep application code small and declarative.

Implementations

impl RunScope

pub fn root<I: Serialize>( name: &str, run_type: RunType, inputs: I, ) -> Result<Self>

pub fn root_value(name: &str, run_type: RunType, inputs: Value) -> Self

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

pub fn with_context(self, ctx: &TraceContext) -> Self

pub fn tracer(&self) -> &Tracer

pub fn tracer_mut(&mut self) -> &mut Tracer

pub fn child<I: Serialize>( &self, name: &str, run_type: RunType, inputs: I, ) -> Result<Self>

pub fn child_value(&self, name: &str, run_type: RunType, inputs: Value) -> Self

pub async fn post_start(&mut self) -> Result<()>

Posts the run start to LangSmith. Safe to call multiple times.

pub async fn end_ok<O: Serialize>(self, outputs: O) -> Result<()>

Ends the run successfully and PATCHes it (best-effort).

pub async fn end_error( self, error: impl ToString, outputs: Option<Value>, ) -> Result<()>

Ends the run with error and PATCHes it (best-effort).
