Implementations

impl<'a, A> DeleteOne<A>

where A: 'a + ActiveModelTrait,

pub fn exec<C>( self, db: &'a C, ) -> impl Future<Output = Result<DeleteResult, DbErr>> + 'a

where C: ConnectionTrait,

Execute a DELETE operation on one ActiveModel

pub fn exec_with_returning<C>( self, db: &'a C, ) -> impl Future<Output = Result<Option<<<A as ActiveModelTrait>::Entity as EntityTrait>::Model>, DbErr>> + 'a

where C: ConnectionTrait,

Execute an delete operation and return the deleted model

Panics

Panics if the database backend does not support DELETE RETURNING
