Implementations

impl FSSetXattrPolicy

pub const AlwaysSet: Self

Set the value, regardless of previous state.

pub const MustCreate: Self

Set the value, but fail if the extended attribute already exists.

pub const MustReplace: Self

Set the value, but fail if the extended attribute doesn’t already exist.

pub const Delete: Self

Delete the value, failing if the extended attribute doesn’t exist.

Trait Implementations

impl Clone for FSSetXattrPolicy

fn clone(&self) -> FSSetXattrPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FSSetXattrPolicy

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

Formats the value using the given formatter.

impl Encode for FSSetXattrPolicy

const ENCODING: Encoding = NSUInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for FSSetXattrPolicy

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 FSSetXattrPolicy

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

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

fn partial_cmp(&self, other: &FSSetXattrPolicy) -> 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 FSSetXattrPolicy

const ENCODING_REF: Encoding

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