Implementations

impl CFString

pub fn from_str(string: &str) -> CFRetained<CFString>

Available on crate feature CFString only.

Creates a new CFString from a str.

pub fn from_static_str(string: &'static str) -> CFRetained<CFString>

Available on crate feature CFString only.

Creates a new CFString from a 'static str.

This may be slightly more efficient than CFString::from_str, as it may be able to re-use the existing buffer (since we know it won’t be deallocated).

Methods from Deref<Target = CFType>

pub fn downcast_ref<T: ConcreteType>(&self) -> Option<&T>

Attempt to downcast the type to that of type T.

This is the reference-variant. Use CFRetained::downcast if you want to convert a retained type. See also ConcreteType for more details on which types support being converted to.

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CFString

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

Formats the value using the given formatter.

impl Deref for CFString

type Target = CFType

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for CFString

Formats the value using the given formatter.

impl Hash for CFString

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 Message for CFString

fn retain(&self) -> Retained<Self>

where Self: Sized,

Increment the reference count of the receiver.

impl Ord for CFString

Available on crate feature CFString only.

fn cmp(&self, other: &Self) -> 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 CFString

fn eq(&self, other: &Self) -> 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 CFString

Available on crate feature CFString only.

fn partial_cmp(&self, other: &Self) -> 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 CFString

const ENCODING_REF: Encoding

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

impl Type for CFString

fn retain(&self) -> CFRetained<Self>

where Self: Sized,

Increment the reference count of the receiver.
