Enum MaskStrategy 

pub enum MaskStrategy {
    Redact,
    Hash,
    Last4,
    Drop,
}

How a matched field is transformed.

Variants

Redact

Shape-preserving redaction: "jane@example.com" → "j***@e***.com", other strings → first char + ***. Default.

Hash

SHA-256 hex of the UTF-8 value — correlatable, unreadable.

Last4

Keep the final 4 characters: "************4242" (PCI PAN style).

Drop

Replace with JSON null — when no residue may remain.

Trait Implementations

impl Clone for MaskStrategy

fn clone(&self) -> MaskStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MaskStrategy

impl Debug for MaskStrategy

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

Formats the value using the given formatter.

impl Eq for MaskStrategy

impl PartialEq for MaskStrategy

fn eq(&self, other: &MaskStrategy) -> 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.
