Trait concrete_core::specification::engines::PlaintextVectorRetrievalEngine

pub trait PlaintextVectorRetrievalEngine<PlaintextVector, Value>: AbstractEngine where
    PlaintextVector: PlaintextVectorEntity, {
    fn retrieve_plaintext_vector(
        &mut self, 
        plaintext: &PlaintextVector
    ) -> Result<Vec<Value>, PlaintextVectorRetrievalError<Self::EngineError>>;
    unsafe fn retrieve_plaintext_vector_unchecked(
        &mut self, 
        plaintext: &PlaintextVector
    ) -> Vec<Value>;
}

A trait for engines retrieving arbitrary values from plaintext vectors.

Semantics

This pure operation generates a vec of arbitrary values from the input plaintext vector. By arbitrary here, we mean that Value can be any type that suits the backend implementor (an integer, a struct wrapping integers, a struct wrapping foreign data or any other thing).

Formal Definition

Required methods

fn retrieve_plaintext_vector(
    &mut self,
    plaintext: &PlaintextVector
) -> Result<Vec<Value>, PlaintextVectorRetrievalError<Self::EngineError>>

Retrieves arbitrary values from a plaintext vector.

unsafe fn retrieve_plaintext_vector_unchecked(
    &mut self,
    plaintext: &PlaintextVector
) -> Vec<Value>

Unsafely retrieves arbitrary values from a plaintext vector.

Safety

For the general safety concerns regarding this operation, refer to the different variants of PlaintextVectorRetrievalError. For safety concerns specific to an engine, refer to the implementer safety section.
