Enum SchemaDataTransformation 

pub enum SchemaDataTransformation {
    ExplicitRowOps(Vec<SchemaMigrationRowOp>),
}

SchemaDataTransformation

SchemaDataTransformation describes the data rewrite portion of one schema migration descriptor. The first slice accepts explicit row rewrites only; derivation engines can add richer variants later without changing db::migration execution.

Variants

ExplicitRowOps(Vec<SchemaMigrationRowOp>)
