Struct CKRecordSavePolicy 

#[repr(transparent)]
pub struct CKRecordSavePolicy(pub NSInteger);

Available on crate feature CKModifyRecordsOperation only.

Locally edited keys are sent to the server, updating the record if the server record has not been modified. This is the default and recommended save policy for regular use. This policy compares the record change tag with the server record, and may return CKErrorServerRecordChangedif the server record has been modified, for example by another device. Note: A CKSharerecord is always treated as CKRecordSaveIfServerRecordUnchanged,regardless of the savePolicyof the operation that modifies the share.

Locally edited keys are written to the server, updating the record even if the server record has been modified. Note: This policy should be used with care, as it can overwrite changes made by other devices. Any previously committed change to the server, for example by other devices, will always be overwritten by the locally changed value. Note: A CKSharerecord is always treated as CKRecordSaveIfServerRecordUnchanged,regardless of the savePolicyof the operation that modifies the share. For non-CKShare records, this policy does not compare the record change tag and therefore will not return CKErrorServerRecordChanged

All local keys are written to the server, updating the record even if the server record has been modified. Note: This policy should be used with care. Any previously committed change to the server, for example by other devices, will be overwritten by the local value. Keys present only on the server remain unchanged. There are two common ways in which a server record will contain keys not present locally: 1 - Another client may have added a new key to the record since it was fetched. 2 - If desiredKeyswas used with the fetch / query that returned this record, only a portion of the record’s keys may have been downloaded. Note: A CKSharerecord is always treated as CKRecordSaveIfServerRecordUnchanged,regardless of the savePolicyof the operation that modifies the share. For non-CKShare records, this policy does not compare the record change tag and therefore will not return CKErrorServerRecordChanged

pub const IfServerRecordUnchanged: Self

pub const ChangedKeys: Self

pub const AllKeys: Self

Does not compare record change tags

Trait Implementations

impl Clone for CKRecordSavePolicy

fn clone(&self) -> CKRecordSavePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CKRecordSavePolicy

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

Formats the value using the given formatter.

impl Encode for CKRecordSavePolicy

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for CKRecordSavePolicy

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 CKRecordSavePolicy

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

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

fn partial_cmp(&self, other: &CKRecordSavePolicy) -> 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 RefEncode for CKRecordSavePolicy

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Copy for CKRecordSavePolicy

impl Eq for CKRecordSavePolicy
