Enum EncryptionType 

pub enum EncryptionType {
    Deterministic,
    Randomized,
}

Encryption type for Always Encrypted columns.

Determines how data is encrypted and what operations are supported.

Variants

Deterministic

Deterministic encryption: same plaintext → same ciphertext.

Supports:

• Equality comparisons (WHERE col = @param)
• JOIN operations
• GROUP BY
• DISTINCT
• Indexing

Security note: Reveals data patterns; less secure than randomized.

Randomized

Randomized encryption: same plaintext → different ciphertext each time.

Maximum security but does NOT support:

• Any comparisons (equality, range, etc.)
• JOIN operations on encrypted column
• GROUP BY or DISTINCT
• Indexing

Implementations

impl EncryptionType

pub fn algorithm_name(&self) -> &'static str

Returns the algorithm identifier used in metadata.

pub fn from_sys_columns_value(value: i32) -> Option<Self>

Parse from the numeric value stored in sys.columns.

Trait Implementations

impl Clone for EncryptionType

fn clone(&self) -> EncryptionType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EncryptionType

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

Formats the value using the given formatter.

impl PartialEq for EncryptionType

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