Trait IsEmptyProperty 

pub trait IsEmptyProperty {
    // Required method
    fn is_empty_property(&self) -> bool;
}

The “empty” property of a collection-like type.

This property is used by the implementation of the AsssertEmptiness assertions.

Required Methods

fn is_empty_property(&self) -> bool

Returns whether the collection-like value is empty.
