Module sqlx_migrator::migration

Module defining migration trait To create own implement migration trait for type

Example

use sqlx_migrator::error::Error;
use sqlx_migrator::migration::Migration;
use sqlx_migrator::operation::Operation;
use sqlx_migrator::sqlx::Sqlite;

struct ExampleMigration;

impl Migration<Sqlite> for ExampleMigration {
    fn app(&self) -> &str {
        "example"
    }

    fn name(&self) -> &str {
        "first_migration"
    }

    fn parents(&self) -> Vec<Box<dyn Migration<Sqlite>>> {
        vec![]
    }

    fn operations(&self) -> Vec<Box<dyn Operation<Sqlite>>> {
        vec![]
    }

    fn replaces(&self) -> Vec<Box<dyn Migration<Sqlite>>> {
        vec![]
    }

    fn run_before(&self) -> Vec<Box<dyn Migration<Sqlite>>> {
        vec![]
    }

    fn is_atomic(&self) -> bool {
        true
    }
}
