    ) -> Result<()> { ... }
}

Element type of a cuVS device buffer or tensor.

Implemented for f32, f64, i8, u8, i32, and i64. The sealed supertrait CudfType restricts implementations to this crate.

Required Associated Constants

const DLPACK_CODE: u8

DLPack type code used, with DLPACK_BITS and one lane, to describe tensors of this element to cuVS.

const DLPACK_BITS: u8

DLPack element width in bits.

const INTEROP_TYPE: InteropTypeId

RAPIDS interop type a prepared cuDF column must carry to be read as a tensor of this element.

Provided Methods

fn valid_native_input(_values: &[Self]) -> bool

Returns whether host values are valid native cuVS input.

Floating elements require finite values; integer elements accept every value.

fn validate_native_buffer( _buffer: &CudfDeviceBuffer, _operation: &'static str, ) -> Result<()>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
