Struct QueueIterator

Source 
pub struct QueueIterator<'s, S: NorFlash, CI: CacheImpl> { /* private fields */ }
Expand description

An iterator-like interface for peeking into data stored in flash with the option to pop it.

Implementations§

Source§

impl<'s, S: NorFlash, CI: CacheImpl> QueueIterator<'s, S, CI>

Source

pub async fn next<'d, 'q>( &'q mut self, data_buffer: &'d mut [u8], ) -> Result<Option<QueueIteratorEntry<'s, 'd, 'q, S, CI>>, Error<S::Error>>

Get the next entry.

If there are no more entries, None is returned.

The data_buffer has to be large enough to be able to hold the largest item in flash.
