Shared capability metadata for rate backends.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

canonical_name: &'static str

Canonical backend family name.

display_label: Arc<str>

Human-readable backend label.

trace_strategy: RateBackendTraceStrategy

VM/AIXI trace strategy for this backend family.

supports_biased_entropy: bool

Whether biased/plugin entropy is supported.

supports_frozen_conditioning: bool

Whether generic frozen-conditioning is supported.

supports_rate_coded_compression: bool

Whether generic rate-coded compression wrapping is supported.

supports_native_bit_prediction: bool

Whether this backend has a direct native bit predictor rather than a byte-symbol adaptation over {0,1}.

supports_byte_prefix_mass: bool

Whether this backend can expose its byte PDF as a lazy binary prefix mass.

supports_efficient_byte_packed_bit_sessions: bool

Whether repeated byte-packed bit-session prefix queries remain practical without a replay-heavy fallback.

supports_reversible_bit_updates: bool

Whether bit observations can be undone exactly after update.

contains_zpaq: bool

Whether the backend graph contains any ZPAQ component.

method_family: Option<MethodBackendFamily>

Whether this is a method-backed neural family.
