pub fn with_new_goal( &mut self, cx: X, input: <X as Cx>::Input, inspect: &mut <D as Delegate>::ProofTreeBuilder, prove_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.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
