Trait AccelDtype 

pub trait AccelDtype:
    Copy
    + Send
    + Sync
    + 'static
    + Debug {
    type Scalar: Copy + Send + Sync + 'static + Debug;

    const KIND: DType;
    const SIZE: usize;
    const NAME: &'static str;

    // Required methods
    fn zero() -> Self;
    fn one() -> Self;
    fn nan() -> Option<Self>;
}

Marker for any numeric type that can be a typed device buffer element across atomr-accel backends.

AccelDtype is intentionally narrower than what individual backends can support. cuBLAS f64 GEMM is gated by a GemmSupported marker on the CUDA side; this trait says only that the type is a recognised dtype.

Required Associated Constants

const KIND: DType

Runtime discriminant.

const SIZE: usize

Bytes per element including representation padding.

const NAME: &'static str

Human-readable name used in tracing and error messages.

Required Associated Types

type Scalar: Copy + Send + Sync + 'static + Debug

Companion scalar type for host-side parameters (alpha/beta, mean/std, scaling factors). Self for full-precision dtypes; f32 for fp8 / fp4 wrappers because the upstream APIs accept f32 scales.

Required Methods

fn zero() -> Self

fn one() -> Self

fn nan() -> Option<Self>

Some(NaN) for floats, None for integers.

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.
