Struct SearchGraph

Source 
pub struct SearchGraph<D, X = X>
where
    D: Delegate<Cx = X>,
    X: Cx,
{
    root_depth: AvailableDepth,
    stack: IndexVec<StackDepth, StackEntry<X>>,
    provisional_cache: HashMap<<X as Cx>::Input, Vec<ProvisionalCacheEntry<X>>, BuildHasherDefault<FxHasher>>,
    _marker: PhantomData<D>,
}

Implementations§

Source§

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

Source

pub fn new(root_depth: usize) -> SearchGraph<D, X>

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.
