Expand description

An immutable string in one of a variety of encodings.

Implementations§

source§

impl CFString

source

pub fn new(string: &str) -> CFString

Creates a new CFString instance from a Rust string.

source

pub fn from_static_string(string: &'static str) -> CFString

Like CFString::new, but references a string that can be used as a backing store by virtue of being statically allocated.

source

pub fn char_len(&self) -> CFIndex

Returns the number of characters in the string.

Trait Implementations§

impl FromStr for CFString

source§

fn from_str(string: &str) -> Result<CFString, ()>

The associated error which can be returned from parsing.
source§

impl<'a> PartialEq<&'a str> for CFString

source§

fn eq(&self, other: &&str) -> 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 TCFType for CFString

§

type Ref = *const __CFString

The reference type wrapped inside this type.
source§

fn as_concrete_TypeRef(&self) -> CFStringRef

Returns the object as its concrete TypeRef.
source§

unsafe fn wrap_under_get_rule(reference: CFStringRef) -> Self

Returns an instance of the object, wrapping the underlying CFTypeRef subclass. Use this when following Core Foundation’s “Get Rule”. The reference count is bumped.
source§

fn as_CFTypeRef(&self) -> CFTypeRef

Returns the object as a raw CFTypeRef. The reference count is not adjusted.
source§

unsafe fn wrap_under_create_rule(reference: CFStringRef) -> Self

Returns an instance of the object, wrapping the underlying CFTypeRef subclass. Use this when following Core Foundation’s “Create Rule”. The reference count is not bumped.
source§

fn type_id() -> CFTypeID

Returns the type ID for this class.
source§

fn as_CFType(&self) -> CFType

Returns the object as a wrapped CFType. The reference count is incremented by one.
source§

fn into_CFType(self) -> CFType
where Self: Sized,

Returns the object as a wrapped CFType. Consumes self and avoids changing the reference count.
source§

fn retain_count(&self) -> CFIndex

Returns the reference count of the object. It is unwise to do anything other than test whether the return value of this method is greater than zero.
source§

fn type_of(&self) -> CFTypeID

Returns the type ID of this object.
source§

fn show(&self)

Writes a debugging version of this object on standard error.
source§

fn instance_of<OtherCFType: TCFType>(&self) -> bool
