Implementations

impl CKRecordZoneEncryptionScope

pub const PerRecord: Self

Zone uses per-record encryption keys for any encrypted values on a record or share.

This is the default encryption scope for a record zone.

pub const PerZone: Self

Zone uses per-zone encryption keys for encrypted values across all records and the zone-wide share, if present.

This is an optional optimization that can reduce the overall storage used by encryption keys in a zone. Note that:

• Record zones using per-zone encryption only support zone-wide sharing.
• Encryption scope can only be assigned at zone creation and cannot be changed for the lifetime of the zone.
• The server will not return zones using per-zone encryption to device OS versions older than the corresponding API availability version.
• An older OS trying to overwrite an existing zone using per-zone encryption due to a naming collision will result in a .serverRejectedRequest error.
• On device OS upgrade, your application is responsible for fetching database changes via CKFetchDatabaseChangesOperation with a nil sync token to ensure it has received all the zones available to it from the server.

Trait Implementations

impl Clone for CKRecordZoneEncryptionScope

fn clone(&self) -> CKRecordZoneEncryptionScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CKRecordZoneEncryptionScope

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

Formats the value using the given formatter.

impl Encode for CKRecordZoneEncryptionScope

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for CKRecordZoneEncryptionScope

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 CKRecordZoneEncryptionScope

fn cmp(&self, other: &CKRecordZoneEncryptionScope) -> 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 CKRecordZoneEncryptionScope

fn eq(&self, other: &CKRecordZoneEncryptionScope) -> 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 CKRecordZoneEncryptionScope

fn partial_cmp(&self, other: &CKRecordZoneEncryptionScope) -> 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.
