MmapStorage

Struct MmapStorage 

Source
pub struct MmapStorage { /* private fields */ }
Expand description

Memory-mapped storage backend.

Provides ultra-fast access to chain data via memory-mapped files. All data is persisted immediately (append-only) and can be accessed without deserialization overhead using rkyv.
