Struct ModelValidationErrors 

Source 
pub struct ModelValidationErrors(/* private fields */);
Expand description

Convert ModelValidationErrors (pretty) into a DbErr (ugly) for database handling.

Because DbErr is used in model hooks and we implement the hooks in the trait, we MUST use DbErr, so we need to “hide” a representation of the error in DbErr::Custom, so that it can be unpacked later down the stream, in the central error response handler.

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>
