pub trait Identity {
    // Required methods
    fn columns() -> Vec<String>;
    fn set_column(&mut self, column: &str, value: &SqlArg) -> Result<()>;
}

Trait to provide the entity type for a key. This is only used for ergonomics of the api.

fn set_column(&mut self, column: &str, value: &SqlArg) -> Result<()>

Sets the value for an identity column

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
