Hook execution context

Fields§

§step: usize§layer_name: String§tensor_shape: Vec<usize>§is_forward: bool§metadata: HashMap<String, String>§loss: Option<f64>

Current training loss, if the caller has reported one via HookManager::set_loss. None (rather than a fabricated 0.0 or a stale value) means no loss has been reported yet for this session – HookCondition::LossThreshold never fires on a hook it has no real data to evaluate.

§grad_norm: Option<f64>

Current gradient norm, if reported via HookManager::set_gradient_norm. See loss for the None semantics.

§memory_mb: Option<f64>

Current memory usage in MB, if reported via HookManager::set_memory_mb. See loss for the None semantics.
