Trait AuditSink 

pub trait AuditSink: Send + Sync {
    // Required method
    fn emit<'life0, 'async_trait>(
        &'life0 self,
        event: AuditEntry,
    ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>
       where 'life0: 'async_trait,
             Self: 'async_trait;
}

Append-only sink for governance AuditEntry records.

Every governance decision produces one entry. The sink is write-only from the runtime’s perspective: it persists entries in order so the hash-chained audit log stays verifiable. Backends may batch or buffer internally, but emit must not reorder entries relative to the calls.

Example

use aa_core::storage::{AuditEntry, AuditSink, Result};
use async_trait::async_trait;

/// A sink that discards every entry (useful as a test double).
struct NullAuditSink;

#[async_trait]
impl AuditSink for NullAuditSink {
    async fn emit(&self, _event: AuditEntry) -> Result<()> {
        Ok(())
    }
}

Required Methods

fn emit<'life0, 'async_trait>( &'life0 self, event: AuditEntry, ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>

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

Persist a single audit entry.

Takes ownership of event because the sink is the entry’s final destination. Returns StorageError::Backend when the entry could not be durably recorded.

Dyn Compatibility

This trait is dyn compatible.

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