Trait fungui::ConvertValue

pub trait ConvertValue<E: Extension>: Sized {
    type RefType: ?Sized;

    fn from_value(v: Value<E>) -> Option<Self>;
    fn from_value_ref(v: &Value<E>) -> Option<&Self::RefType>;
    fn to_value(v: Self) -> Value<E>;
}

Types that can be converted to and from a value

Required Associated Types

type RefType: ?Sized

The reference type of this value.

Useful for types like String where the reference type is str

Required Methods

fn from_value(v: Value<E>) -> Option<Self>

Tries to convert from the passed value to this type

fn from_value_ref(v: &Value<E>) -> Option<&Self::RefType>

Tries to convert from the passed value to the reference type.

fn to_value(v: Self) -> Value<E>

Converts the value into a Value
