Struct RpcResponseShape 

pub struct RpcResponseShape { /* private fields */ }

Expectations derived from the actual pending application request, never from data echoed by the server. Use optional query shape from a trusted locally parsed plan; the protocol preflight does not parse SQL.

Implementations

impl RpcResponseShape

pub fn from_request(request: &Request) -> Self

pub fn with_query_shape( self, columns: usize, limit: Option<u64>, aggregate: bool, ) -> Result<Self, &'static str>

Refine a query using its validated pending plan. Invalid refinements fail instead of becoming a less restrictive expectation.
