Struct core_foundation::data::CFData

pub struct CFData(_);

A byte buffer.

Methods

impl CFData

pub fn from_buffer(buffer: &[u8]) -> CFData

pub fn bytes<'a>(&'a self) -> &'a [u8]

Returns a pointer to the underlying bytes in this data. Note that this byte buffer is read-only.

pub fn len(&self) -> CFIndex

Returns the length of this byte buffer.

Trait Implementations

impl ConcreteCFType for CFData

impl TCFType for CFData

type Ref = CFDataRef

The reference type wrapped inside this type.

fn as_concrete_TypeRef(&self) -> CFDataRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: CFDataRef) -> 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.

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: CFDataRef) -> 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.

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

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

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<OtherCFType: TCFType>(&self) -> bool

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

impl<'a> ToVoid<CFData> for &'a CFData

fn to_void(&self) -> *const c_void

impl ToVoid<CFData> for CFData

fn to_void(&self) -> *const c_void

impl ToVoid<CFData> for CFDataRef

fn to_void(&self) -> *const c_void

impl CFPropertyListSubClass for CFData

fn to_CFPropertyList(&self) -> CFPropertyList

Create an instance of the superclass type [CFPropertyList] for this instance.

fn into_CFPropertyList(self) -> CFPropertyList where
    Self: Sized, 

Equal to [to_CFPropertyList], but consumes self and avoids changing the reference count.

impl Drop for CFData

fn drop(&mut self)

Executes the destructor for this type.

impl Clone for CFData

fn clone(&self) -> CFData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for CFData

impl PartialEq<CFData> for CFData

fn eq(&self, other: &CFData) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Debug for CFData

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

Formats the value using the given formatter.

impl Deref for CFData

type Target = [u8]

The resulting type after dereferencing.

fn deref(&self) -> &[u8]

Dereferences the value.
