Trait ArrowPrimitiveVariant

pub(super) trait ArrowPrimitiveVariant: ArrowPrimitiveType {
    // Required method
    fn from_variant(variant: &Variant<'_, '_>) -> Option<Self::Native>;
}

Trait for Arrow primitive types that can be used in the output builder

This just exists to add a generic way to convert from Variant to the primitive type

Required Methods

fn from_variant(variant: &Variant<'_, '_>) -> Option<Self::Native>

Try to extract the primitive value from a Variant, returning None if it cannot be converted

TODO: figure out how to handle coercion/casting

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.
