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 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 + Sized + 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.

Required Methods

fn holder() -> &'static str

database placeholder str,for example: mysql,sqlite = ‘?’,pg=‘$’,mssql=‘p’

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.
