powerio-dist 0.11.1

//! The codes this crate emits.
//!
//! The record itself lives in `powerio-core`, below this crate and below the
//! `.pio.json` document model, so a distribution finding reaches a package
//! without a translation step. What lives here is the distribution side
//! registry: one [`DiagnosticInfo`] per code, declared once, so an emission
//! site names an entry rather than a loose string.
//!
//! Codes are families, not one per site: what differs between two sites of a
//! family is which object or property it was, which belongs in `details`.

// The collector is crate-private implementation support, not API: each
// emitting crate carries its own copy (src/collect.rs) and never exports it.
