Struct conjure_oxide::solver::Solver

pub struct Solver<A, State = Init>
where
    A: SolverAdaptor,
    State: SolverState,
{ /* private fields */ }

An abstract representation of a constraints solver.

Solver provides a common interface for interacting with a constraint solver. It also abstracts over solver-specific datatypes, handling the translation to/from conjure_core::ast types for a model and its solutions.

Details of how a model is solved is specified by the SolverAdaptor. This includes: the underlying solver used, the translation of the model to a solver compatible form, how solutions are translated back to conjure_core::ast types, and how incremental solving is implemented. As such, there may be multiple SolverAdaptor implementations for a single underlying solver: e.g. one adaptor may give solutions in a representation close to the solvers, while another may attempt to rewrite it back into Essence.
