Trait Implementations

impl<'env> Drop for Txn<'env>

fn drop(&mut self)

A method called when the value goes out of scope.

impl<'env> Transaction for Txn<'env>

fn iter<'a, K: Representable, V: Representable>(&'a self,
                                                db: &'a Db<K, V>,
                                                key: Option<K>,
                                                value: Option<V>)
                                                -> Cursor<'a, Self, K, V>

Iterate over a database, starting at the first value larger than or equal to (key, value) (and at the smallest key, or smallest value if one or both of them is None).

fn root<K: Representable, V: Representable>(&mut self,
                                            root: usize)
                                            -> Option<Db<K, V>>

Gets the specified root. At most 508 different roots are allowed.

fn get<'a, K: Representable, V: Representable>(&'a self,
                                               root: &Db<K, V>,
                                               key: K,
                                               value: Option<V>)
                                               -> Option<V>

Get the smallest value associated to key, or returns the given binding if value is Some(..) and is associated to key in the given database.
