Enum MigrationClass 

pub enum MigrationClass {
    Reversible,
    DataLosing,
    Irreversible,
}

Classification of migration operations.

Variants

Reversible

DataLosing

Can apply, rollback may lose data (e.g., DROP COLUMN, DROP TABLE)

Irreversible

Trait Implementations

impl Clone for MigrationClass

fn clone(&self) -> MigrationClass

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MigrationClass

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MigrationClass

fn eq(&self, other: &MigrationClass) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
