pub struct CGDataProvider(_);

Methods

impl CGDataProvider

pub fn type_id() -> CFTypeID

pub fn from_buffer(buffer: Arc<Vec<u8>>) -> Self

Creates a data provider from the given reference-counted buffer.

The CGDataProvider object takes ownership of the reference. Once the data provider is destroyed, the reference count of the buffer is automatically decremented.

Creates a copy of the data from the underlying CFDataProviderRef.
