Expand description

The DNSIterable trait represents a set of records that can be iterated over.

Required Methods§

source

fn next(self) -> Option<Self>where Self: Sized,

Returns the next record, or None if there aren’t any left.

source

fn offset(&self) -> Option<usize>

Returns the offset of the current RR, or None if we haven’t started iterating yet or if the current record has been deleted.

In order to check for the later, please use is_tombstone() instead for clarity.

source

fn offset_next(&self) -> usize

Returns the offset right after the current RR.

source

fn set_offset(&mut self, offset: usize)

Sets the offset of the current RR.

source

fn set_offset_next(&mut self, offset: usize)

Sets the offset of the next RR.

source

fn invalidate(&mut self)

Prevents access to the current record. This is useful after a delete operation: from a user perspective, the current iterator doesn’t point to a valid RR any more.
