Trait ConnectionInitializer

pub trait ConnectionInitializer {

    const END_VERSION: u32;

    // Required methods
    fn init(&self, tx: &Transaction<'_>) -> Result<()>;
    fn upgrade_from(&self, conn: &Transaction<'_>, version: u32) -> Result<()>;

    // Provided methods

}

Required Associated Constants

const NAME: &'static str

const END_VERSION: u32

Required Methods

fn init(&self, tx: &Transaction<'_>) -> Result<()>

fn upgrade_from(&self, conn: &Transaction<'_>, version: u32) -> Result<()>

Provided Methods

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.
