Struct TracedHandlerOptions

pub struct TracedHandlerOptions<T> {
    pub name: Option<&'static str>,
    pub event: Option<LambdaEvent<T>>,
    pub kind: Option<String>,
    pub attributes: Option<HashMap<String, String>>,
    pub links: Option<Vec<Link>>,
    pub parent_context: Option<Context>,
    pub get_carrier: Option<Arc<dyn Fn(&Value) -> HashMap<String, String> + Send + Sync>>,
}

Options for configuring traced Lambda handlers.

This struct provides a builder-style interface for configuring how spans are created and attributed for Lambda function invocations. All fields are optional and have sensible defaults.

Example

use lambda_otel_lite::TracedHandlerOptions;
use lambda_runtime::LambdaEvent;
use serde_json::Value;

let event = LambdaEvent::new(Value::Null, Default::default());
let options = TracedHandlerOptions::default()
    .with_name("my-handler")
    .with_event(event)
    .with_kind("SERVER".to_string());

Fields

name: Option<&'static str>

Name of the span

event: Option<LambdaEvent<T>>

Lambda event containing both payload and context

kind: Option<String>

Optional span kind. Defaults to SERVER

attributes: Option<HashMap<String, String>>

Optional custom attributes to add to the span

links: Option<Vec<Link>>

Optional span links

parent_context: Option<Context>

Optional parent context for trace propagation

get_carrier: Option<Arc<dyn Fn(&Value) -> HashMap<String, String> + Send + Sync>>

Optional function to extract carrier from event for context propagation
