Trait RuntimeHostCompoundProvider 

pub trait RuntimeHostCompoundProvider<S>: Send + Sync {
    // Required method
    fn pull(
        &self,
        solution: &S,
        limits: RuntimeProviderLimits,
    ) -> Vec<RawProviderCandidate>;
}

Object-safe lazy pull boundary for host-language callbacks only.

A Python implementation performs Python::attach(...).unwrap_or_else( panic_with_py_err) inside this method. Core never catches/re-wraps that panic, preserving the original Python exception and traceback for direct and retained solves. open_cursor, size, and validate_cursor must not call this method.

Required Methods

fn pull( &self, solution: &S, limits: RuntimeProviderLimits, ) -> Vec<RawProviderCandidate>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
