Enum MigrationIssue 

#[non_exhaustive]
pub enum MigrationIssue {
    Unknown(String),
    OutOfOrder(String),
}

A mismatch between the declared migrations and the bookkeeping table, reported by MigratorTrait::check.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown(String)

A migration recorded as applied that MigratorTrait::migrations no longer declares, for example after a deployment was rolled back to an older binary or a migration was renamed.

OutOfOrder(String)

A pending migration declared before one that is already applied, typically after two branches that each added a migration were merged; up applies it after the later one.
