A database driver.

This trait encapsulates a complete set of traits that implement a driver for a specific database (e.g., MySQL, PostgreSQL).

Required Associated Constants

const NAME: &'static str

The display name for this database driver.

const URL_SCHEMES: &'static [&'static str]

The schemes for database URLs that should match this driver.

Required Associated Types

type Connection: Connection<Database = Self>

The concrete Connection implementation for this database.

type TransactionManager: TransactionManager<Database = Self>

The concrete TransactionManager implementation for this database.

type Row: Row<Database = Self>

The concrete Row implementation for this database.

type QueryResult: 'static + Send + Sync + Default + Extend<Self::QueryResult>

The concrete QueryResult implementation for this database.

type Column: Column<Database = Self>

The concrete Column implementation for this database.

type TypeInfo: TypeInfo

The concrete TypeInfo implementation for this database.

type Value: Value<Database = Self> + 'static

The concrete type used to hold an owned copy of the not-yet-decoded value that was received from the database.

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.
