Trait IsSetVal

Source 
pub(super) trait IsSetVal {
    // Required method
    fn is_set_val() -> bool;
}
Expand description

A trait to differentiate between BTreeMap and BTreeSet values. Returns true only for type SetValZST, false for all other types (blanket implementation). TypeId requires a 'static lifetime, use of this trait avoids that restriction.

Required Methods§

fn is_set_val() -> bool

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
