Trait Fields 

pub trait Fields {
    // Required methods
    fn name(&self, index: usize) -> Option<&str>;
    fn get(&self, name: &str) -> Option<Shown<'_>>;

    // Provided method
    fn names(&self) -> Box<dyn Iterator<Item = &str> + '_> { ... }
}

Named and ordered as the type’s JSON; #[derive(ReadModel)] writes them for a read model.

Required Methods

fn name(&self, index: usize) -> Option<&str>

fn get(&self, name: &str) -> Option<Shown<'_>>

Provided Methods

fn names(&self) -> Box<dyn Iterator<Item = &str> + '_>

Overridden where name(index) walks from the start, so a walk over all fields stays linear.

Dyn Compatibility

This trait is dyn compatible.

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