Convenience helpers that map sqlx errors into PremixError.

Required Methods

fn save_result<'a, E>( &'a mut self, executor: E, ) -> impl Future<Output = Result<(), PremixError>>

where E: IntoExecutor<'a, DB = DB>,

Save the model and return PremixError on failure.

fn update_result<'a, E>( &'a mut self, executor: E, ) -> impl Future<Output = Result<UpdateResult, PremixError>>

where E: IntoExecutor<'a, DB = DB>,

Update the model and return PremixError on failure.

fn delete_result<'a, E>( &'a mut self, executor: E, ) -> impl Future<Output = Result<(), PremixError>>

where E: IntoExecutor<'a, DB = DB>,

Delete the model and return PremixError on failure.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
