Implementations§

source§

impl<D, X> SearchGraph<D, X>
where D: Delegate<Cx = X>, X: Cx,

source

pub fn new(mode: SolverMode) -> SearchGraph<D, X>

source

pub fn solver_mode(&self) -> SolverMode

source

pub fn is_empty(&self) -> bool

source

pub fn debug_current_depth(&self) -> usize

The number of goals currently in the search graph. This should only be used for debugging purposes.

source

pub fn with_new_goal( &mut self, cx: X, input: <X as Cx>::Input, inspect: &mut <D as Delegate>::ProofTreeBuilder, evaluate_goal: impl FnMut(&mut SearchGraph<D, X>, &mut <D as Delegate>::ProofTreeBuilder) -> <X as Cx>::Result, ) -> <X as Cx>::Result

Probably the most involved method of the whole solver.

Given some goal which is proven via the prove_goal closure, this handles caching, overflow, and coinductive cycles.
