Trait RobotsPolicyGuard 

pub trait RobotsPolicyGuard: Send + Sync {
    // Required methods
    fn name(&self) -> &'static str;
    fn decide<'life0, 'life1, 'async_trait>(
        &'life0 self,
        url: &'life1 str,
    ) -> Pin<Box<dyn Future<Output = Result<RobotsDecision>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Port trait: ask a guard whether a URL is permitted under the configured RobotsPolicy.

Adapters must be Send + Sync so they can be stored in an Arc and shared between the recon path and the production path. The guard is invoked at pipeline-build time (so forbidden URLs surface before any production traffic) and again at execute time (so policy drift between spec-build and run is caught).

Required Methods

fn name(&self) -> &'static str

Stable name for diagnostics — usually the upstream source ("manual", "robots_txt", "cached").

fn decide<'life0, 'life1, 'async_trait>( &'life0 self, url: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<RobotsDecision>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Decide whether a single URL may be fetched.

Errors

Returns crate::domain::error::GraphError::ExecutionFailed if the guard cannot reach its data source (e.g. network failure during a live robots.txt lookup).

Dyn Compatibility

This trait is dyn compatible.

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