Struct polars_core::utils::NoNull

pub struct NoNull<T> { /* fields omitted */ }

Just a wrapper structure. Useful for certain impl specializations This is for instance use to implement impl<T> FromIterator<T::Native> for NoNull<ChunkedArray<T>> as Option<T::Native> was already implemented: impl<T> FromIterator<Option<T::Native>> for ChunkedArray<T>

Implementations
