Enum DatabaseBackend 

#[non_exhaustive]
pub enum DatabaseBackend {
    MySql,
    Postgres,
    Sqlite,
}

Identifies which SQL dialect is in use. Passed around so that sea_query-built statements can be rendered with the right placeholders, quoting, and feature support. Available variants are gated by feature flags — see the crate-level documentation.

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.

MySql

MySQL / MariaDB.

Postgres

PostgreSQL.

Sqlite

SQLite.
