Enum StorageEngine 

pub enum StorageEngine {
    Redb,
    Sqlite,
}

The engine behind a data directory’s store/. Chosen once, when the directory is created; recorded as its FORMAT_VERSION; never guessed.

Variants

Redb

Legacy format-1 redb store. New stores never select it; the variant is retained only so older memory can be opened and migrated.

Sqlite

WAL-mode SQLite: several processes may open the same store. This is the only engine used for new memory.

Implementations

impl StorageEngine

pub const fn format_version(self) -> u32

The FORMAT_VERSION this engine stamps.

pub const fn is_compiled(self) -> bool

Both known formats remain readable during the compatibility window.

pub const fn name(self) -> &'static str
