Enum DriftAction 

pub enum DriftAction {
    NotifyOnly,
    ReduceConfidence,
    ResetModel,
    ResetPreprocessor,
    ReplaceWithBaseline,
    IncreaseAdaptationRate,
}

The action to take when drift is detected.

This enum is returned by a DriftStrategy and executed by DriftAwareModel.

Variants

NotifyOnly

Record the event but do not change model behavior. This is the safest default and should be used when the cost of a wrong reset exceeds the cost of a slow adaptation.

ReduceConfidence

Lower the confidence associated with subsequent predictions. The interpretation is left to the caller (e.g. widen prediction intervals or flag predictions as uncertain).

ResetModel

Reset the wrapped model’s parameters to their initial state. Use when the concept drift is severe enough that relearning from scratch is faster than incremental adaptation.

ResetPreprocessor

Reset the preprocessor’s running statistics (e.g. StandardScaler mean and variance). Useful when feature distributions have shifted but the target relationship remains similar.

ReplaceWithBaseline

Replace the current model with a baseline model. The replacement logic is handled by the caller; this action signals intent.

IncreaseAdaptationRate

Increase the model’s adaptation rate (e.g. raise the learning rate) so it can relearn faster on the new distribution. The exact mechanism is model-dependent.

Implementations

impl DriftAction

pub const fn as_str(&self) -> &'static str

Returns a short, stable string identifier.

Possible values: "notify_only", "reduce_confidence", "reset_model", "reset_preprocessor", "replace_with_baseline", "increase_adaptation_rate".

pub const fn is_destructive(self) -> bool

Returns true if this action modifies the model or preprocessor state.

NotifyOnly and ReduceConfidence return false; all others return true.
