Struct QueryExpr

pub struct QueryExpr<C: Commitment> { /* private fields */ }

A QueryExpr represents a Proof of SQL query that can be executed against a database. It consists of a DynProofPlan for provable components and a vector of OwnedTablePostprocessing for the rest.

Implementations

impl<C: Commitment> QueryExpr<C>

pub fn new( proof_expr: DynProofPlan<C>, postprocessing: Vec<OwnedTablePostprocessing>, ) -> Self

Creates a new QueryExpr with the given DynProofPlan and OwnedTablePostprocessing.

pub fn try_new( ast: SelectStatement, default_schema: Identifier, schema_accessor: &dyn SchemaAccessor, ) -> Result<Self, ConversionError>

Parse an intermediate AST SelectStatement into a QueryExpr.

pub fn proof_expr(&self) -> &DynProofPlan<C>

Immutable access to this query’s provable filter expression.

pub fn postprocessing(&self) -> &[OwnedTablePostprocessing]

Immutable access to this query’s post-proof result transform expression.

Trait Implementations

impl<C: Commitment> Debug for QueryExpr<C>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, C> Deserialize<'de> for QueryExpr<C>

where C: Deserialize<'de> + Commitment,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<C: PartialEq + Commitment> PartialEq for QueryExpr<C>

fn eq(&self, other: &QueryExpr<C>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<C> Serialize for QueryExpr<C>

where C: Serialize + Commitment,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
