Provable nodes in the provable AST.

Required Methods§

Source

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

Count terms used within the Query’s proof

Source

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

Form components needed to verify and proof store into VerificationBuilder

Source

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

Return all the result column fields

Source

fn get_column_references( &self, ) -> IndexSet<ColumnRef, BuildHasherDefault<AHasher>>

Return all the columns referenced in the Query

Source

fn get_table_references( &self, ) -> IndexSet<TableRef, BuildHasherDefault<AHasher>>

Return all the tables referenced in the Query

Provided Methods§

Source

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

Check if the input table is empty

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
