Trait SelectValue 

pub trait SelectValue: Sized {
    const MANY: bool = false;

    // Required method
    fn extract(data: &MessageComponentData) -> Result<Self, String>;
}

A typed select handler parameter (on:select:name=|ctx, picked: Vec<Color>| ..): the selected values as String, Snowflake, resolved User, Role or PartialChannel, or a #[derive(Choice)] enum; one (required), Option or Vec.

Provided Associated Constants

const MANY: bool = false

Several selections (a Vec)

Required Methods

fn extract(data: &MessageComponentData) -> Result<Self, String>

Reads the selected values; an error message when they do not fit the type

Dyn Compatibility

This trait is not dyn compatible.

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