// SPDX-License-Identifier: MIT
//! Await-safe alternative to `let _guard = span.enter();` using
//! [`otel_bootstrap::Spanned`] / [`otel_bootstrap::in_span`].
//!
//! Shows the pattern a `*_span(...)`-style attribute-recording helper (like
//! sealwiz-core's `telemetry::wrap_span`) should hand its caller: build the
//! span with attributes up front, then run the async work under it via
//! `Instrument` instead of returning a bare `Span` for `.enter()`.
//!
//! Run with:
//! ```text
//! cargo run --example spanned --features testing
//! ```

async fn load_master() -> Result<&'static str, &'static str> {
    Ok("master-key")

    // Free-function form.
    let span = tracing::info_span!("sealwiz.wrap", sealwiz.namespace = "ns-1");
    let master = in_span(span, load_master()).await.expect("load succeeds");

    // Builder form — reads better at multi-line call sites.
