Trait ChoiceOptions 

pub trait ChoiceOptions:
    Copy
    + Eq
    + 'static {
    const ALL: &'static [Self];

    // Required methods
    fn name(self) -> &'static str;
    fn description(self) -> Option<Content>;

    // Provided method
    fn from_name(name: &str) -> Option<Self> { ... }
}

A fixed set of Choice options backed by a Rust type, usually a fieldless enum.

Implement it with choice_options! or by hand. The option names are the strings sent to the API and returned in answers, and must be unique.

Required Associated Constants

const ALL: &'static [Self]

Every option, in the order it is sent.

Required Methods

fn name(self) -> &'static str

The option name used on the wire.

fn description(self) -> Option<Content>

When this option applies; None sends the name alone.

Provided Methods

fn from_name(name: &str) -> Option<Self>

Parses an option name from an answer.

Dyn Compatibility

This trait is not dyn compatible.

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