Implementations

impl NSFileProviderCreateItemOptions

pub const MayAlreadyExist: Self

The imported item may already exist.

This can happen because:

1. The imported item was found on disk after the synchronisation state was lost, for example following the restoration of a backup, or the migration to a new device.

2. Two directories are merged together, due to the extension returning the same itemIdentifier for both directories on the createItem completion handler. Each child resulting of the merge may be recreated with the mayAlreadyExist option. This allows the extension to recursively merge directories.

The Extension should assess whether the item could actually be a disk representation of an already existing item.

The best user experience is to match the requested item to one on the server, if the extension is able to confirm that the disk item is representing an item already on the server.

Given that this flag may be set when the system is reimporting all items from disk, it is advised that the Extension attempts assessment methods for each item in order from cheapest to most expensive (in terms of CPU and network), in order to avoid unnecessary work.

When all the items pending reimport have been processed, the system will call -[NSFileProviderExtension importDidFinishWithCompletionHandler:].

pub const DeletionConflicted: Self

This item is recreated after the system failed to apply a deletion requested by the extension because the item was found to be edited locally. This happens only if the edit wasn’t yet known by the system at the time the deletion was requested.

impl NSFileProviderCreateItemOptions

pub const fn empty() -> Self

Get a flags value with all bits unset.

pub const fn all() -> Self

Get a flags value with all known bits set.

pub const fn bits(&self) -> NSUInteger

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

pub const fn from_bits(bits: NSUInteger) -> Option<Self>

Convert from a bits value.

This method will return None if any unknown bits are set.

pub const fn from_bits_truncate(bits: NSUInteger) -> Self

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: NSUInteger) -> Self

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

pub fn insert(&mut self, other: Self)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: Self)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: Self)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: Self, value: bool)

Call insert when value is true or remove when value is false.

pub const fn union(self, other: Self) -> Self

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: Self) -> Self

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl NSFileProviderCreateItemOptions

pub const fn iter(&self) -> Iter<NSFileProviderCreateItemOptions>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<NSFileProviderCreateItemOptions>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
