Struct schema_connector::Migration

source · 
pub struct Migration(/* private fields */);
Expand description

A boxed migration, opaque to the schema engine core. The connectors are sole responsible for producing and understanding migrations — the core just orchestrates.

Implementations§

source§

impl Migration

source

pub fn new<T: 'static + Send + Sync>(migration: T) -> Self

Type-erase a migration.

source

pub fn downcast_ref<T: 'static>(&self) -> &T

Should never be used in the core, only in connectors that know what they put there.
