//! Storage-variant dispatch for [`NumericIndex`].
//!
//! `NumericIndexInner<T>` is the enum that selects across the three
//! storage backends (`Mutable`, `Immutable`, `Mmap`) and forwards each
//! operation to the active variant. The forwarding impls are split
//! across sibling modules:
//!
//! - [`lifecycle`]: construction, persistence, file listing, cache
//!   control, and `remove_point`.
//! - [`read_ops`]: read-path forwarding — value lookups, telemetry,
//!   RAM accounting, `is_on_disk`.
//! - [`trait_impls`]: [`PayloadFieldIndex`], [`PayloadFieldIndexRead`],
//!   and [`StreamRange`] implementations (the query logic itself lives
//!   in the shared [`query`](super::query) helpers).
//! - [`read_only`]: [`ReadOnlyNumericIndexInner`] — the read-only
//!   counterpart enum over the appendable and immutable backends.
//!
//! [`NumericIndex`]: super::NumericIndex
//! [`PayloadFieldIndex`]: crate::index::field_index::PayloadFieldIndex
//! [`PayloadFieldIndexRead`]: crate::index::field_index::PayloadFieldIndexRead
//! [`StreamRange`]: super::StreamRange
//! [`ReadOnlyNumericIndexInner`]: read_only::ReadOnlyNumericIndexInner
