Attribute Macro migration_op 

#[migration_op]

Available on crate feature db only.

An attribute macro that defines a custom migration operation.

This macro simplifies writing custom migration operations by allowing you to write them as regular async functions. It handles the necessary pinning and boxing of the return type to make it compatible with the migration engine.

Examples

use cot::db::Result;
use cot::db::migrations::{MigrationContext, migration_op};

#[migration_op]
async fn my_migration(ctx: MigrationContext<'_>) -> Result<()> {
    // Your migration logic here
    Ok(())
}
