Struct Response 

pub struct Response<E: EntityKind> { /* private fields */ }

Response

Public facade over a materialized query result. Wraps the core response and exposes only safe, policy-aware operations. Any returned Id<E> values are public identifiers for correlation, reporting, and lookup only.

Implementations

impl<E: EntityKind> Response<E>

pub const fn from_core(inner: CoreEntityResponse<E>) -> Self

Construct a facade response from a core response.

pub const fn count(&self) -> u32

pub const fn exists(&self) -> bool

pub fn require_one(&self) -> Result<(), Error>

Require exactly one row.

pub fn require_some(&self) -> Result<(), Error>

Require at least one row.

pub fn entity(self) -> Result<E, Error>

Return the single entity.

pub fn try_entity(self) -> Result<Option<E>, Error>

Return zero or one entity.

pub fn entities(self) -> Vec<E>

Return all entities.

pub fn require_id(self) -> Result<Id<E>, Error>

Return the single identity.

This key is a public identifier and does not grant access or authority.

pub fn try_id(self) -> Result<Option<Id<E>>, Error>

Return zero or one primary key.

IDs are safe to transport and log; verification is always explicit and contextual.

pub fn ids(&self) -> impl Iterator<Item = Id<E>> + '_

Borrow an iterator over primary keys for correlation, reporting, and lookup.

pub fn contains_id(&self, id: &Id<E>) -> bool

Check whether the response contains the given primary key.

impl<E: Debug + EntityKind> Debug for Response<E>

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

Formats the value using the given formatter.
