Enum WriteFailure 

pub enum WriteFailure {
    Warn,
    Halt,
    Custom(Arc<dyn Fn(WriteFailurePhase, &MemvidError) -> WriteFailureAction + Send + Sync>),
}

What the MemvidPersistHook does when a frame fails to write.

Defaults to WriteFailure::Warn so existing behaviour is preserved: the failure is logged via tracing::warn! and the turn continues. Operators who would rather halt the agent than silently lose memory writes can switch to WriteFailure::Halt; advanced callers can install a WriteFailure::Custom callback (e.g. to update a counter, page on an SLO breach, or fall back to a sidecar log).

Variants

Warn

Log the failure at WARN and continue the turn. Default — matches pre-0.2 behaviour.

Halt

Log the failure at ERROR, emit a tracing event, and signal the agent to stop via HookAction::Terminate on the next return path. Useful when the agent’s value is bounded by durable memory.

Custom(Arc<dyn Fn(WriteFailurePhase, &MemvidError) -> WriteFailureAction + Send + Sync>)

Run a caller-provided callback with the failure phase and error. Returning WriteFailureAction::Continue keeps the turn alive; WriteFailureAction::Halt stops the agent.
