Struct SpanAttributes

pub struct SpanAttributes {
    pub kind: Option<String>,
    pub attributes: HashMap<String, String>,
    pub links: Vec<Link>,
    pub carrier: Option<HashMap<String, String>>,
}

Data extracted from a Lambda event for span creation.

This struct contains all the information needed to create and configure an OpenTelemetry span, including custom attributes, span kind, links, and context propagation headers.

Example

use lambda_otel_lite::SpanAttributes;
use std::collections::HashMap;

let mut attributes = HashMap::new();
attributes.insert("custom.field".to_string(), "value".to_string());

let span_attrs = SpanAttributes {
    kind: Some("CLIENT".to_string()),
    attributes,
    ..SpanAttributes::default()
};

Fields

kind: Option<String>

Optional span kind (defaults to SERVER if not provided)

attributes: HashMap<String, String>

Custom attributes to add to the span

links: Vec<Link>

Optional span links for connecting related traces

carrier: Option<HashMap<String, String>>

Optional carrier headers for context propagation (W3C Trace Context format)
