[−][src]Trait gdnative_core::FromVariant

pub trait FromVariant: Sized {
    fn from_variant(variant: &Variant) -> Result<Self, FromVariantError>;
}

Types that can be converted from a Variant.

`Option<T>` and `MaybeNot<T>`

Option<T> requires the Variant to be T or Nil, in that order. For looser semantics, use MaybeNot<T>, which will catch all variant values that are not T as well.

`Vec<T>`

The FromVariant implementation for Vec<T> only allow homogeneous arrays. If you want to manually handle potentially heterogeneous values e.g. for error reporting, use VariantArray directly or compose with an appropriate wrapper: Vec<Option<T>> or Vec<MaybeNot<T>>.

Deriving `FromVariant`

The derive macro provides implementation consistent with derived ToVariant. See ToVariant for detailed documentation.
