Struct TatrOptions 

#[non_exhaustive]
pub struct TatrOptions {
    pub model_dir: Option<PathBuf>,
    pub ort_dylib: Option<PathBuf>,
    pub intra_threads: usize,
    pub sessions_per_model: usize,
    pub detector_regions_only: bool,
    /* private fields */
}

TATR table structure, opted into per call (track B, P3).

Set on ExtractOptions with ExtractOptions::with_tatr. When set, every table region is offered to the Table Transformer first: where it fires its cells are the region’s table, and where it does not the current grid runs unchanged. Unset, extraction never touches the model and reads byte for byte as without the option.

The knobs mirror the shared layer’s RuntimeConfig without naming it: that type only exists behind the ort feature, and this one must exist on every build so the option, its refusal, and the test seam below compile everywhere. Behind ort-tables the engine builds the runtime config from these fields; without it, asking for TATR is an OptionsError::TatrNeedsOrtTables, never a silent fast run.

#[non_exhaustive], like every option type here: start from Default and assign the fields. All fields are Eq, so ExtractOptions keeps its Eq.

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.

model_dir: Option<PathBuf>

Explicit model dir; wins over the env var and the default, as the shared layer’s model_dir does. Default None: resolve it there.

ort_dylib: Option<PathBuf>

Explicit ONNX Runtime library; wins over the env var and the default. Default None: resolve it there.

intra_threads: usize

ONNX Runtime intra-op threads per session. Default 4.

sessions_per_model: usize

Sessions per model: a pool so parallel pages do not serialise on one session. Default 1.

detector_regions_only: bool

TATR acts only on regions from a detector or teacher box. Default false: every region [crate::learned::tables::rebuild_region] rebuilds is offered to TATR, whether the learned pass or a teacher box drew it. The switch P4 restricts with once the detector lands.
