Trait Choice 

pub trait Choice: Sized {
    const TYPES: &'static [&'static str];

    // Required methods
    fn decode_as(
        code: &str,
        key: &str,
        o: &mut Obj<'_>,
        d: &mut Decoder,
    ) -> Option<Self>;
    fn encode_into(&self, base: &str, w: &mut ObjWriter);
}

A [x] choice element: an enum with one variant per allowed type.

Required Associated Constants

const TYPES: &'static [&'static str]

The FHIR type codes the element allows, in definition order. The JSON key is the element name followed by the capitalised code (value + Quantity).

Required Methods

fn decode_as( code: &str, key: &str, o: &mut Obj<'_>, d: &mut Decoder, ) -> Option<Self>

Read the variant for type code from key key of o.

fn encode_into(&self, base: &str, w: &mut ObjWriter)

Write the chosen variant under base plus its type suffix.

Dyn Compatibility

This trait is not dyn compatible.

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