Trait PickerSelection 

pub trait PickerSelection<T: 'static>: Clone + 'static {
    // Required methods
    fn current(&self) -> Option<T>;
    fn choose(&self, value: T);
}

How a picker reads and writes its selection: a required value (picker) or an optional one (picker_optional). Implemented by the two adapters below, never by apps.

Required Methods

fn current(&self) -> Option<T>

Tracked read of the current value, None when nothing is chosen.

fn choose(&self, value: T)

The user chose value.

Dyn Compatibility

This trait is not dyn compatible.

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