Embeddable migration management
migrant_lib allows defining and embedding management of migration in your shipped app.
rust
config.use_migrations(vec![
FileMigration::with_tag("initial")?
.up("migrations/initial/up.sql")?
.down("migrations/initial/down.sql")?
.boxed(),
FileMigration::with_tag("second")?
.up("migrations/second/up.sql")?
.down("migrations/second/down.sql")?
.boxed(),
FnMigration::with_tag("custom")?
.up(migrations::Custom::up)
.down(migrations::Custom::down)
.boxed(),
])?;
Migrations can be defined as files or functions. Migration files must exist at runtime.
Migration tags must all be unique. Function migrations must have the signature
fn(DbConn) -> Result<(), Box<std::error::Error>>. See the
programmable example
for a working sample.
Migrations management identical to migrant cli tool can also be embedded.
This method only supports file-base migrations generated by migrant_lib (or migrant cli). See the
embedded example
for a working sample.
