csi-webserver-core 0.1.1

//! Pluggable capability seam for optional, out-of-tree CSI extensions.
//!
//! The open core knows only the protocols, presets, and data-format labels it
//! ships with. A [`CsiProfile`] lets an embedder extend those sets at
//! construction time without the core naming any of the extra values: the
//! server injects one profile (default [`StandardCsiProfile`], a no-op) into
//! [`AppState`](crate::state::AppState) / the per-device serial task, and the
//! config routes and Parquet sink consult it where they previously hard-coded
//! chip-specific behaviour.
//!
//! All methods are defaulted so the standard profile is empty and an embedder
//! overrides only what it needs.
