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".
