Struct MultilinearExtensionIndex

source 
pub struct MultilinearExtensionIndex<'a, U, FW>
where
    U: UnderlierType + PackScalar<FW>,
    FW: Field,
{ /* private fields */ }
Expand description

Data structure that indexes multilinear extensions by oracle ID.

A crate::oracle::MultilinearOracleSet indexes multilinear polynomial oracles by assigning unique, sequential oracle IDs. The caller can get the MultilinearExtension defined natively over a subfield. This is possible because the MultilinearExtensionIndex::get method is generic over the subfield type and the struct itself only stores the underlying data.
