Trait ComputeVTable

Source 
pub trait ComputeVTable<V: VTable> {
    // Required method
    fn invoke(
        array: &V::Array,
        compute_fn: &ComputeFn,
        args: &InvocationArgs<'_>,
    ) -> VortexResult<Option<Output>>;
}

Required Methods§

Source

fn invoke( array: &V::Array, compute_fn: &ComputeFn, args: &InvocationArgs<'_>, ) -> VortexResult<Option<Output>>

Dynamically invokes the given compute function on the array.

Returns None if the compute function is not supported by this array, otherwise attempts to invoke the function.

This can be useful to support compute functions based on some property of the function, without knowing at compile-time what that function is. For example, any elementwise function can be pushed-down over a dictionary array and evaluated only on the unique values.

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.
