§fn nullable(self) -> Nullable<Self>
fn nullable(self) -> Nullable<Self>
Converts this potentially non-null expression into one which is treated
as nullable. This method has no impact on the generated SQL, and is only
used to allow certain comparisons that would otherwise fail to compile. Read more
§fn assume_not_null(self) -> AssumeNotNull<Self>
fn assume_not_null(self) -> AssumeNotNull<Self>
Converts this potentially nullable expression into one which will be assumed
to be not-null. This method has no impact on the generated SQL, however it will
enable you to attempt deserialization of the returned value in a non-
Option
