Trait ICCameraDeviceDownloadDelegate 

pub unsafe trait ICCameraDeviceDownloadDelegate: NSObjectProtocol {
    // Provided methods
    unsafe fn didDownloadFile_error_options_contextInfo(
        &self,
        file: &ICCameraFile,
        error: Option<&NSError>,
        options: &NSDictionary<NSString, AnyObject>,

}

Available on crate feature ICCameraDevice only.

The object passed in as ‘downloadDelegate’ in the ‘requestDownloadFile:options:downloadDelegate:didDownloadSelector:contextInfo:’ message must conform to ICCameraDeviceDownloadDelegate protocol.

Provided Methods

unsafe fn didDownloadFile_error_options_contextInfo( &self, file: &ICCameraFile, error: Option<&NSError>, options: &NSDictionary<NSString, AnyObject>, context_info: *mut c_void, )

where Self: Sized + Message,

Available on crate features ICCameraFile and ICCameraItem only.

This message is sent to the delegate when the requested download operation is complete.

Safety

• options generic should be of the correct type.
• context_info must be a valid pointer or null.

unsafe fn didReceiveDownloadProgressForFile_downloadedBytes_maxBytes( &self, file: &ICCameraFile, downloaded_bytes: off_t, max_bytes: off_t, )

where Self: Sized + Message,

Available on crate features ICCameraFile and ICCameraItem and libc only.

This message is sent to the delegate to provide status of the download operation.
