Trait WitnessClient 

pub trait WitnessClient: Send + Sync {
    // Required methods
    fn submit_event(
        &self,
        endpoint: &str,
        event: &[u8],
    ) -> impl Future<Output = Result<Vec<u8>, NetworkError>> + Send;
    fn query_receipts(
        &self,
        endpoint: &str,
        prefix: &Prefix,
    ) -> impl Future<Output = Result<Vec<Vec<u8>>, NetworkError>> + Send;
}

Submits key events and queries receipts from the witness infrastructure.

Witnesses observe and receipt key events to provide accountability. Implementations handle the transport details; the domain provides serialized events and receives receipts as opaque byte arrays.

Usage:

use auths_core::ports::network::WitnessClient;

async fn witness_inception(client: &dyn WitnessClient, endpoint: &str, event: &[u8]) {
    let receipt = client.submit_event(endpoint, event).await.unwrap();
}

Required Methods

fn submit_event( &self, endpoint: &str, event: &[u8], ) -> impl Future<Output = Result<Vec<u8>, NetworkError>> + Send

Submits a serialized key event to a witness and returns the receipt bytes.

Args:

• endpoint: The witness endpoint identifier.
• event: The serialized key event bytes.

Usage:

let receipt = client.submit_event("witness-1.example.com", &event_bytes).await?;

fn query_receipts( &self, endpoint: &str, prefix: &Prefix, ) -> impl Future<Output = Result<Vec<Vec<u8>>, NetworkError>> + Send

Queries all receipts a witness holds for the given KERI prefix.

Args:

• endpoint: The witness endpoint identifier.
• prefix: The KERI prefix to query receipts for.

Usage:

let prefix = Prefix::new_unchecked("EAbcdef...".into());
let receipts = client.query_receipts("witness-1.example.com", &prefix).await?;

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
