Trait FissionViewField 

pub trait FissionViewField {
    type View<'a>
       where Self: 'a;

    // Required method
    fn view_field<'a>(value: &'a Self) -> Self::View<'a>;
}

Maps a state field type to the view returned by generated view accessors.

#[derive(FissionStateView)] implements this trait for nested state structs. Built-in scalar and collection types map to ValueView.

Required Associated Types

type View<'a> where Self: 'a

Required Methods

fn view_field<'a>(value: &'a Self) -> Self::View<'a>

Dyn Compatibility

This trait is not dyn compatible.

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