Enum AutoVacuumMode 

#[non_exhaustive]
#[repr(i32)]
pub enum AutoVacuumMode {
    None = 0,
    Full = 1,
    Incremental = 2,
}

Available on crate feature __sqlite-shared only.

The auto_vacuum mode of a database, controlling whether and when SQLite reclaims freed pages back to the file.

The mode is stored in the database file, not the connection. Full and Incremental can be switched between at any time, but changing from or to None only takes effect on a database with no tables yet, or after a subsequent VACUUM rewrites the file.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None = 0

Freed pages stay on the freelist and the file never shrinks (default).

Full = 1

Freed pages are reclaimed and the file truncated at every commit.

Incremental = 2

Freelist bookkeeping is kept, pages are reclaimed only when incremental_vacuum runs.
