Struct Schema

Source

pub struct Schema<'c> { /* private fields */ }

Expand description

The handle a migration uses to change the schema. Renders sea-query statements for the running backend, with a raw-SQL escape hatch.

Implementations§

Source §

impl Schema<'_>

Source

pub fn backend(&self) -> DbBackend

Source

pub async fn exec<S: SchemaStatementBuilder>( &mut self, stmt: S, ) -> CoreResult<()>

Runs a sea-query schema statement (Table::create/alter/drop, Index::create, …). Takes the statement by value and renders it to SQL before awaiting, so the (non-Send) statement is not held across the await point.

Source

pub async fn raw(&mut self, sql: &str) -> CoreResult<()>

Runs raw SQL, for anything the builder does not express. Portability is the caller’s responsibility.
