Struct leveldb_rs::DBIterator

pub struct DBIterator { /* fields omitted */ }

This structure represents an iterator over the database. Note that since the next() function is bounded by a lifetime, it does not (quite) conform to the Iterator trait. To get this, use the alloc() helper.

Methods

impl DBIterator

fn next<'a>(&'a mut self) -> Option<(&'a [u8], &'a [u8])>

Return the next key/value pair from this iterator.

fn alloc(self) -> DBIteratorAlloc

Return an instance of DBIteratorAlloc, an iterator that implements the Iterator trait, but allocates new Vecs for each item. Note that this consumes the DBIterator instance, so it can't be used again.

fn seek_to_first(&mut self)

Seek to the beginning of the database.

fn seek_to_last(&mut self)

Seek to the end of the database.

fn seek(&mut self, key: &[u8])

Seek to the first key in the database that is at or past the given target key.

fn prev(&mut self)

Move to the previous item in the database.

Trait Implementations

impl Drop for DBIterator

fn drop(&mut self)

A method called when the value goes out of scope.
