Required Methods

async fn load(&self, context: &[u8]) -> Result<u32, Self::Error>

Load the stored counter for context, or 0 if missing.

async fn store(&self, context: &[u8], value: u32) -> Result<(), Self::Error>

Persist a counter value for context.

async fn flush(&self) -> Result<(), Self::Error>

Flush any buffered state to durable storage.

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.
