Struct CFData 

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

Safe wrapper around a retained Core Foundation CFData reference.

Implementations

impl CFData

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

Adopts a +1 retained CFData pointer and returns None for null.

Safety

A non-null ptr must be a live CFData pointer of the exact dynamic type carrying one retain transferred to this wrapper. The caller must not release or separately adopt that transferred retain.

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

Retains a +0 borrowed CFData pointer and returns an owned wrapper.

Safety

A non-null ptr must be a live CFData pointer of the exact dynamic type for the duration of the retain call.

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

Borrows the raw +0 Core Foundation pointer while self remains alive.

pub fn type_id() -> usize

Returns the Core Foundation type ID for CFData.

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased 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.
