Struct GlobalPreprocessed 

Source 
pub struct GlobalPreprocessed<SC: SGC> {
    pub commitment: Commitment<SC>,
    pub instances: Vec<Option<PreprocessedInstanceMeta>>,
    pub matrix_to_instance: Vec<usize>,
}
Expand description

Global preprocessed data shared by all batch-STARK instances.

This batches all per-instance preprocessed traces into a single Pcs commitment, while keeping a mapping from instance index to matrix index and per-matrix metadata.

Fields§

§commitment: Commitment<SC>

Single Pcs commitment to all preprocessed traces (one matrix per instance that defines preprocessed columns).

§instances: Vec<Option<PreprocessedInstanceMeta>>

For each STARK instance, optional metadata describing its preprocessed trace inside the global commitment.

instances[i] == None means instance i has no preprocessed columns.

§matrix_to_instance: Vec<usize>

Mapping from preprocessed matrix index to the corresponding instance index.

This allows building per-matrix opening schedules and routing opened values back to instances.
