Provable nodes in the provable AST.

Required Methods

fn count( &self, builder: &mut CountBuilder<'_>, accessor: &dyn MetadataAccessor, ) -> Result<(), ProofError>

Count terms used within the Query’s proof

fn get_length(&self, accessor: &dyn MetadataAccessor) -> usize

The length of the input table

fn get_offset(&self, accessor: &dyn MetadataAccessor) -> usize

The offset of the query, that is, how many rows to skip before starting to read the input table

fn verifier_evaluate( &self, builder: &mut VerificationBuilder<'_, C>, accessor: &dyn CommitmentAccessor<C>, result: Option<&OwnedTable<C::Scalar>>, ) -> Result<(), ProofError>

Form components needed to verify and proof store into VerificationBuilder

fn get_column_result_fields(&self) -> Vec<ColumnField>

Return all the result column fields

fn get_column_references(&self) -> IndexSet<ColumnRef>

Return all the columns referenced in the Query

Provided Methods

fn is_empty(&self, accessor: &dyn MetadataAccessor) -> bool

Check if the input table is empty
