Struct sequential_storage::queue::PopIterator

pub struct PopIterator<'d, S: MultiwriteNorFlash> { /* private fields */ }

Expand description

Iterator for pop’ing elements in the queue.

Implementations§

impl<'d, S: MultiwriteNorFlash> PopIterator<'d, S>

pub fn next<'m>( &mut self, data_buffer: &'m mut [u8] ) -> Result<Option<&'m mut [u8]>, Error<S::Error>>

Pop the next data.

The data is written to the given data_buffer and the part that was written is returned. It is valid to only use the length of the returned slice and use the original data_buffer. The data_buffer may contain extra data on ranges after the returned slice. You should not depend on that data.

If the data buffer is not big enough an error is returned.
