Struct DlogReaderStorage 

pub struct DlogReaderStorage { /* private fields */ }

Implementations

impl DlogReaderStorage

pub unsafe fn init( flags: u32, notify: unsafe extern "C" fn(*mut c_void), cookie: *mut c_void, ) -> impl PinInit<Self, Infallible>

Creates a PinInit initializer for DlogReaderStorage.

Since DlogReaders typically capture containing objects via cookie, they use 2-phase initialization to avoid races in the construction of the DlogReader and the containing object.

Safety

The caller must ensure cookie is valid for notify.

pub fn disconnect(self: Pin<&mut Self>)

Safely disconnects DlogReader.

DlogReaders must be manually stopped via disconnect to avoid reentrancy issues in the DlogReader and its containing object.

This method must be called before the DlogReaderStorage is dropped if it was initialized.

pub fn read( self: Pin<&mut Self>, flags: u32, record: &mut dlog_record_t, actual: &mut usize, ) -> Status

Reads one record from debuglog.

Upon success, returns Status::OK and sets actual to the record’s size. Returns Status::SHOULD_WAIT if there are no records available to read.
