Module storage 

Storage backend trait and implementations.

The StorageBackend trait abstracts over where narinfo metadata and compressed NAR blobs are persisted. Three implementations are provided:

• LocalStorage — local filesystem (default)
• S3Storage — S3-compatible object storage (AWS, MinIO, R2, RustFS)
• StorageIndex — redb ephemeral metadata index (accelerates S3 lookups)

Re-exports

pub use index::StorageIndex;

pub use local::LocalStorage;

pub use s3::S3Storage;
