Trait Migration 

pub trait Migration<X>
where
    X: Executor,
{
    // Required methods
    fn name(&self) -> &'static str;
    fn up<'a>(
        &'a self,
        db: &'a X,
    ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + 'a>>;
}

One migration step. The unique name orders + dedupes it; up performs the change against an executor. Implement this on a struct for bespoke DDL, or use Migrator::create_table for the common “create this entity’s table”.

Required Methods

fn name(&self) -> &'static str

fn up<'a>( &'a self, db: &'a X, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + 'a>>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
