Trait Database

pub trait Database: Optionable<Option = OptionDatabase> {
    type ConnectionType: Connection;

    // Required methods
    fn new_connection(&mut self) -> Result<Self::ConnectionType>;
    fn new_connection_with_opts(
        &mut self,
        opts: impl IntoIterator<Item = (OptionConnection, OptionValue)>,
    ) -> Result<Self::ConnectionType>;
}

A handle to an ADBC database.

Databases hold state shared by multiple connections. This typically means configuration and caches. For in-memory databases, it provides a place to hold ownership of the in-memory database.

Databases must be kept alive as long as any connections exist.

Required Associated Types

type ConnectionType: Connection

Required Methods

fn new_connection(&mut self) -> Result<Self::ConnectionType>

Allocate and initialize a new connection without pre-init options.

fn new_connection_with_opts( &mut self, opts: impl IntoIterator<Item = (OptionConnection, OptionValue)>, ) -> Result<Self::ConnectionType>

Allocate and initialize a new connection with pre-init options.

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.
