Trait FromValue 

pub trait FromValue: Enumeration {
    // Required methods
    fn from_value<'a>(
        value: &'a Self::AssociatedValueType,
    ) -> Result<Self, UnknownAssociatedValueError<'a, Self>>;
    fn from_value_unchecked(value: &Self::AssociatedValueType) -> Self;
}

Returns the first variant (in the declaration order) associated with the value. More info at Enumeration.

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.
