Struct core_foundation::string::CFString [−][src]
pub struct CFString(_);
An immutable string in one of a variety of encodings.
Methods
impl CFString
[src]
impl CFString
pub fn new(string: &str) -> CFString
[src]
pub fn new(string: &str) -> CFString
Creates a new CFString
instance from a Rust string.
pub fn from_static_string(string: &'static str) -> CFString
[src]
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.
pub fn char_len(&self) -> CFIndex
[src]
pub fn char_len(&self) -> CFIndex
Returns the number of characters in the string.
Trait Implementations
impl Drop for CFString
[src]
impl Drop for CFString
impl TCFType for CFString
[src]
impl TCFType for CFString
type Ref = CFStringRef
The reference type wrapped inside this type.
fn as_concrete_TypeRef(&self) -> CFStringRef
[src]
fn as_concrete_TypeRef(&self) -> CFStringRef
Returns the object as its concrete TypeRef.
unsafe fn wrap_under_get_rule(reference: CFStringRef) -> Self
[src]
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. Read more
fn as_CFTypeRef(&self) -> CFTypeRef
[src]
fn as_CFTypeRef(&self) -> CFTypeRef
Returns the object as a raw CFTypeRef
. The reference count is not adjusted.
unsafe fn wrap_under_create_rule(reference: CFStringRef) -> Self
[src]
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. Read more
fn type_id() -> CFTypeID
[src]
fn type_id() -> CFTypeID
Returns the type ID for this class.
fn as_CFType(&self) -> CFType
[src]
fn as_CFType(&self) -> CFType
Returns the object as a wrapped CFType
. The reference count is incremented by one.
fn into_CFType(self) -> CFType where
Self: Sized,
[src]
fn into_CFType(self) -> CFType where
Self: Sized,
Returns the object as a wrapped CFType
. Consumes self and avoids changing the reference count. Read more
fn retain_count(&self) -> CFIndex
[src]
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. Read more
fn type_of(&self) -> CFTypeID
[src]
fn type_of(&self) -> CFTypeID
Returns the type ID of this object.
fn show(&self)
[src]
fn show(&self)
Writes a debugging version of this object on standard error.
fn instance_of<OtherCFType: TCFType>(&self) -> bool
[src]
fn instance_of<OtherCFType: TCFType>(&self) -> bool
Returns true if this value is an instance of another type.
impl Clone for CFString
[src]
impl Clone for CFString
fn clone(&self) -> CFString
[src]
fn clone(&self) -> CFString
Returns a copy of the value. Read more
fn clone_from(&mut self, source: &Self)
1.0.0[src]
fn clone_from(&mut self, source: &Self)
Performs copy-assignment from source
. Read more
impl PartialEq for CFString

impl PartialEq for CFString
fn eq(&self, other: &CFString) -> bool
[src]
fn eq(&self, other: &CFString) -> bool
This method tests for self
and other
values to be equal, and is used by ==
. Read more
fn ne(&self, other: &Rhs) -> bool
1.0.0[src]
fn ne(&self, other: &Rhs) -> bool
This method tests for !=
.
