Attribute Macro db_up::migrations

#[migrations]

Attribute macro for automatically generating a db_up::MigrationStore

The macro takes one required literal string parameter representing the directory containing the migration files. Each file must be named like V<version>_<name>.sql, where <version> is a valid integer and <name> is some name describing what the migration does.

Example:

use db_up_codegen::migrations;

#[migrations("examples/migrations/")]
struct Migrations {}

pub fn main() {
    let migration_store = Migrations {};
    println!("migrations: {:?}", migration_store.changelogs());
}
