Implementations

impl CFData

pub fn from_bytes(bytes: &[u8]) -> CFRetained<Self>

Available on crate feature CFBase only.

Creates a new CFData from a byte slice.

pub fn from_static_bytes(bytes: &'static [u8]) -> CFRetained<Self>

Available on crate feature CFBase only.

Creates a new CFData from a 'static byte slice.

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

pub fn len(&self) -> usize

Available on crate feature CFBase only.

The number of bytes contained by the CFData.

pub fn is_empty(&self) -> bool

Available on crate feature CFBase only.

Whether the CFData is empty.

pub unsafe fn as_bytes_unchecked(&self) -> &[u8]

Available on crate feature CFBase only.

The underlying bytes in the CFData.

Safety

The CFData must not be mutated for the lifetime of the returned string. Consider using to_vec instead if this requirement is a bit difficult to uphold.

pub fn to_vec(&self) -> Vec<u8>

Available on crate features CFBase and alloc only.

Copy the contents of the CFData into a new Vec.

Methods from Deref<Target = CFType>

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

Available on crate feature CFBase only.

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.

Trait Implementations

impl Borrow<AnyObject> for CFData

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFData> for CFMutableData

fn borrow(&self) -> &CFData

Immutably borrows from an owned value.

impl Borrow<CFType> for CFData

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CFData

Available on crate feature CFBase only.

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CFData

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

Formats the value using the given formatter.

impl Deref for CFData

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CFData

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 CFData

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CFData

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 Type for CFData

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

where Self: Sized,
