Struct core_foundation::string::CFString

pub struct CFString(_);

An immutable string in one of a variety of encodings.

Methods

impl CFString

fn new(string: &str) -> CFString

Creates a new CFString instance from a Rust string.

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.

fn char_len(&self) -> CFIndex

Returns the number of characters in the string.

Trait Implementations

impl Clone for CFString

fn clone(&self) -> CFString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Drop for CFString

fn drop(&mut self)

A method called when the value goes out of scope.

impl TCFType<CFStringRef> for CFString

fn as_concrete_TypeRef(&self) -> CFStringRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: CFStringRef) -> CFString

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.

fn as_CFTypeRef(&self) -> CFTypeRef

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

unsafe fn wrap_under_create_rule(obj: CFStringRef) -> CFString

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.

fn type_id() -> CFTypeID

Returns the type ID for this class.

fn as_CFType(&self) -> CFType

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

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.

fn type_of(&self) -> CFTypeID

Returns the type ID of this object.

fn show(&self)

Writes a debugging version of this object on standard error.

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

Returns true if this value is an instance of another type.

impl FromStr for CFString

type Err = ()

The associated error which can be returned from parsing.

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

See also CFString::new for a variant of this which does not return a Result

impl Display for CFString

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Debug for CFString

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

Formats the value using the given formatter.
