Trait FilterReduce 

Source 
pub trait FilterReduce: VTable {
    // Required method
    fn filter(
        array: &Self::Array,
        mask: &Mask,
    ) -> VortexResult<Option<ArrayRef>>;
}

Required Methods§

Source

fn filter(array: &Self::Array, mask: &Mask) -> VortexResult<Option<ArrayRef>>

Filter an array with the provided mask without reading buffers.

This trait is for filter implementations that can operate purely on array metadata and structure without needing to read or execute on the underlying buffers. Implementations should return None if filtering requires buffer access.

§Preconditions

The mask is guaranteed to have the same length as the array.

Additionally, the mask is guaranteed to be a Mask::Values variant (i.e., neither Mask::AllTrue nor Mask::AllFalse).

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.
