Function payload_kind 

pub fn payload_kind(payload: Option<&CanonicalPayload>) -> &'static str

Returns a string representation of the payload kind for logging.

This is a utility function for structured logging to categorize payloads without exposing actual content.

Arguments

• payload - Optional reference to canonical payload

Returns

String describing the payload type: "text", "binary", or "none"

Examples

use ingest::{payload_kind, CanonicalPayload};

let text = Some(CanonicalPayload::Text("hello".to_string()));
assert_eq!(payload_kind(text.as_ref()), "text");

let binary = Some(CanonicalPayload::Binary(vec![1, 2, 3]));
assert_eq!(payload_kind(binary.as_ref()), "binary");

assert_eq!(payload_kind(None), "none");
