Struct IndexInfo 

pub struct IndexInfo {
    pub name: String,
    pub extractor_type: &'static str,
    pub schema_version: u32,
}

Metadata about a registered secondary index.

Returned by Isam::secondary_indices.

Fields

name: String

The name the index was registered under.

extractor_type: &'static str

Fully-qualified type name of the DeriveKey extractor implementation.

Provided by std::any::type_name — suitable for display and logging, but not for persistent storage (the value may change across compiler versions or if the type is renamed or moved).

schema_version: u32

The index schema version stored in the .sidx metadata.

Set to 0 for newly created indices and updated by Isam::migrate_index. Use this to confirm that a migration has been applied, or to detect indices that predate schema versioning.
