Trait ProofFetcher 

pub trait ProofFetcher {
    type Error;

    // Required method
    fn fetch(
        &mut self,
        txid: &str,
        reask: &Reask,
    ) -> Result<Option<Proof>, Self::Error>;
}

The host’s proof transport. The crate declares it but never calls it.

Required Associated Types

type Error

The transport’s own error type.

Required Methods

fn fetch( &mut self, txid: &str, reask: &Reask, ) -> Result<Option<Proof>, Self::Error>

Execute a scheduled re-ask, with no proof represented explicitly. Competitor hints name the txids the host must also reconcile.

Dyn Compatibility

This trait is dyn compatible.

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