pub trait FpElement: KernelDtype + Sealed { }Expand description
8-bit floating-point element types supported by the kernel facade.
Sibling trait to Element (which covers f16 / bf16 / f32 /
F32Strict / f64) and to IntElement (which covers S8 / U8) —
kept separate because the FP8 kernel family has its own MMA
instruction set (mma.sync ... .f32.e4m3.e4m3.f32), arch requirement
(sm_89+), and conversion semantics (saturating-to-max-finite vs the
int family’s saturating-to-INT_MAX).
Sealed because adding a new FP8 variant requires shipping new kernel
instantiations in baracuda-kernels-sys.
KIND is inherited from the KernelDtype supertrait. Pre-Phase-28
code using <T as FpElement>::KIND must update to plain T::KIND
or <T as KernelDtype>::KIND.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
