//! This module contains 3 constants,
//! used for algorithms to distinguish between sqeuential, parallel, or MPI-based computation.
//! Ideally, these constants should belong into one Enum,
//! but at the moment rust does not support const generics for Enums.
/// use single-threaded computation
pub const SEQ_COMPUTATION: usize = 0;
/// use multi-threaded computation, on one machine
pub const PAR_COMPUTATION: usize = 1;
/// use multiple machinges to parallelize computation, via MPI
pub const MPI_COMPUTATION: usize = 2;
/// Convenience function.
///
/// # Panics
///
/// Always, with an explanitory panic message.
