Enum Action 

#[non_exhaustive]
pub enum Action {
    Tokenize,
    Redact,
    FormatPreserve,
    Generalize,
    Preserve,
}

Disposition applied to a detected PII span.

Variant	Restorable	Output shape
Tokenize	Yes	Opaque token: <hex:Class_N>
FormatPreserve	Yes	Realistic-looking pseudonym (e.g., email1.hex@gaze-fake.invalid)
Redact	No	Literal [REDACTED] – original value is gone
Generalize	No	Class label (e.g., [Email]) – original value is gone
Preserve	-	Passes through unchanged

Action is #[non_exhaustive]. Use a wildcard arm in exhaustive matches. When restore is required, use Tokenize or FormatPreserve – Redact and Generalize are irreversible.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Tokenize

Replace PII with a reversible token.

Redact

Replace PII with a non-restorable redaction marker.

FormatPreserve

Replace PII with a reversible format-preserving token.

Generalize

Replace PII with a broader category.

Preserve

Preserve the original value.

Trait Implementations

impl Clone for Action

fn clone(&self) -> Action

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Action

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Action

fn eq(&self, other: &Action) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
