Trait Sqlite3Wal

    // Required methods
    unsafe fn wal_checkpoint(
        &self,
        db: NonNull<Self::Db>,

}

Optional backend extension for WAL helpers.

Safety

Implementations must only operate on valid database handles and obey SQLite checkpoint and WAL-state semantics.

Required Methods

unsafe fn wal_checkpoint( &self, db: NonNull<Self::Db>, db_name: Option<&str>, ) -> Result<()>

unsafe fn wal_checkpoint_v2( &self, db: NonNull<Self::Db>, db_name: Option<&str>, mode: i32, ) -> Result<(i32, i32)>

unsafe fn wal_frame_count(&self, db: NonNull<Self::Db>) -> Result<Option<u32>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
