Identity Hash

struct Hash128

Two-word digest used as a stable identity for token blocks, media content and adapters.

struct FnvValue

Running state of a host-side 128-bit FNV-1a computation; finishHash() turns it into a Hash128.

Hash128 trt_edgellm::rt::hashOpaqueIdentity(

std::string_view bytes,

cudaStream_t stream,

bool cpuOnly

)

Deterministic 128-bit FNV-1a digest of exact opaque bytes, used as the identity of media content and adapters.

When stream is non-null and cpuOnly is false, payloads above an internal threshold are hashed on the GPU using a parallel chunked kernel. The result is bit-identical to the CPU path. Callers on hot paths with large payloads (raw audio, for instance) should pass a valid stream and set cpuOnly=false.
