pub unsafe extern "C" fn ket_process_exp_value(
    process: &mut Process,
    hamiltonian: *mut Hamiltonian<LogicalQubit>,
    result: &mut usize,
) -> i32
Expand description

Calculates the expected value of the PauliHamiltonian in the Process instance.

§Arguments

  • process - [in] A mutable reference to the Process instance.
  • hamiltonian - [in] A mutable pointer to a PauliHamiltonian.
  • result - [out] A mutable pointer to a usize where the result identifier will be stored.

§Returns

An integer representing the error code. 0 indicates success.

§Safety

This function is marked as unsafe due to the use of raw pointers.
