    // Required method
    fn build(&self, parent: &SealedHeader<Header>) -> Attributes;
}

Factory trait for creating payload attributes.

Enables different strategies for generating payload attributes based on contextual information. Useful for testing and specialized building.

Required Methods

fn build(&self, parent: &SealedHeader<Header>) -> Attributes

Constructs new payload attributes for the given timestamp.
