tess::gpu::GpuBackend Concept Reference

#include <tess/gpu/backend.h>

Concept definition

template<typename B>
concept GpuBackend =
    requires(B& backend, const B& const_backend, const UploadDesc& upload,
             const DispatchDesc& dispatch, const ReadbackDesc& readback) {
      {
        const_backend.capabilities()
      } noexcept -> std::same_as<GpuCapabilities>;
      { backend.upload(upload) } -> std::same_as<bool>;
      { backend.dispatch(dispatch) } -> std::same_as<bool>;
      { backend.readback(readback) } -> std::same_as<bool>;
    }

Detailed Description

Compile-time contract for an optional GPU execution backend.

Operations return false when refused, allowing the authoritative CPU path to take over without interpreting backend-specific errors.
