Struct SqlMigration 

pub struct SqlMigration { /* private fields */ }

A migration whose up and down are raw SQL strings. down is optional; its absence makes the migration irreversible.

Implementations

impl SqlMigration

pub fn new(name: impl Into<String>, up: impl Into<String>) -> Self

pub fn reversible(self, down: impl Into<String>) -> Self

Trait Implementations

impl Migration for SqlMigration

fn name(&self) -> &str

The stable name recorded in the tracking table. Never change it once the migration has shipped.

fn up<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, schema: &'life1 mut Schema<'life2>, ) -> Pin<Box<dyn Future<Output = CoreResult<()>> + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Applies the migration.

fn down<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, schema: &'life1 mut Schema<'life2>, ) -> Pin<Box<dyn Future<Output = CoreResult<()>> + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Reverses the migration. The default marks it irreversible; the runner fills in the module id. Override to make a migration reversible.
