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.

base_dir: PathBuf

Base directory used to resolve relative spec/model paths.

ctw_depth: usize

Default CTW depth when no numeric method is supplied.

fac_ctw_base_depth: usize

Default FAC-CTW base depth when no numeric method is supplied.

fac_ctw_num_percept_bits: usize

Default FAC-CTW percept width.

fac_ctw_encoding_bits: usize

Default FAC-CTW symbol encoding width.

fac_ctw_msb_first: Option<bool>

Optional FAC-CTW MSB-first override for shorthand CLI parsing.

None defers to compile-time default (encoding_bits == 8 → MSB-first).

ppmd_order: usize

Default PPMD order.

ppmd_memory_mb: usize

Default PPMD memory budget in MiB.

sequitur_context_bytes: usize

Default Sequitur context window.

zpaq_method: String

Default ZPAQ rate method.

default_mamba_model_path: Option<String>

Optional default Mamba model path when no method is supplied.

default_rwkv_model_path: Option<String>

Optional default RWKV7 model path when no method is supplied.

particle_default_if_missing_method: bool

Whether particle without a method should build ParticleSpec::default().
