Struct CFData 

pub struct CFData(/* private fields */);

Implementations

impl CFData

pub fn from_raw(ptr: *mut c_void) -> Option<Self>

pub unsafe fn from_raw_retained(ptr: *mut c_void) -> Option<Self>

Retain a borrowed pointer before wrapping it.

Safety

ptr must be NULL or a valid pointer of the expected Core Foundation type.

pub const fn as_ptr(&self) -> *mut c_void

pub fn type_id() -> usize

pub fn into_cf_type(self) -> CFType

impl CFData

pub fn from_bytes<B: AsRef<[u8]>>(bytes: B) -> Self

Copy bytes into a new CFData.

pub fn len(&self) -> usize

Number of bytes stored in the data blob.

pub fn is_empty(&self) -> bool

Whether the data blob is empty.

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

Copy the data into a Rust-owned vector.

Trait Implementations

impl AsCFType for CFData

fn as_ptr(&self) -> *mut c_void

Borrow the underlying Core Foundation object pointer.

fn to_cf_type(&self) -> CFType

Clone this value as an erased CFType.

impl Clone for CFData

fn clone(&self) -> CFData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CFData

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

Formats the value using the given formatter.

impl From<CFData> for CFType

fn from(value: CFData) -> Self

Converts to this type from the input type.

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 PartialEq for CFData

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