Trait DatabaseMetadataSource 

pub(crate) trait DatabaseMetadataSource {
    // Required methods
    fn get_table_sizes(
        &self,
    ) -> impl Send + Future<Output = Result<Vec<TableSize>>>;
    fn get_migration_status(
        &self,
    ) -> impl Send + Future<Output = Result<Vec<MigrationStatus>>>;
}

Data source for database metadata and statistics.

This trait is only implemented by SQL-based storage backends (PostgreSQL and SQLite).

Required Methods

fn get_table_sizes(&self) -> impl Send + Future<Output = Result<Vec<TableSize>>>

Get the sizes of all tables in the database.

fn get_migration_status( &self, ) -> impl Send + Future<Output = Result<Vec<MigrationStatus>>>

Get the status of all deferred background migrations.

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.
