Classification of data for compliance purposes.

Supports multi-framework compliance: HIPAA, GDPR, PCI DSS, SOX, ISO 27001, FedRAMP.

Classification Levels (8 total)

Healthcare (HIPAA):

• PHI: Protected Health Information
• Deidentified: De-identified per HIPAA Safe Harbor

Privacy (GDPR):

• PII: Personally Identifiable Information (GDPR Article 4)
• Sensitive: Special category data (GDPR Article 9) - race, health, biometrics, etc.

Financial (PCI DSS, SOX):

• PCI: Payment Card Industry data (card numbers, CVV, etc.)
• Financial: Financial records subject to SOX regulations

General:

• Confidential: Internal business data, trade secrets
• Public: Publicly available data with no restrictions

Examples: Medical records, diagnoses, lab results, prescriptions

Compliance: HIPAA Privacy Rule, HIPAA Security Rule

Retention: Minimum 6 years after last treatment (HIPAA § 164.530)

Deidentified

Data that has been de-identified per HIPAA Safe Harbor.

Requirements: All 18 HIPAA identifiers removed (§ 164.514(b)(2))

Examples: Anonymized patient datasets, aggregate statistics

Compliance: HIPAA Safe Harbor Method

Trait Implementations

impl Clone for DataClass

fn clone(&self) -> DataClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataClass

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataClass

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DataClass

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DataClass

fn cmp(&self, other: &DataClass) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DataClass

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

impl PartialOrd for DataClass

fn partial_cmp(&self, other: &DataClass) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for DataClass

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for DataClass

impl Eq for DataClass

impl StructuralPartialEq for DataClass
