pub struct StreamTransaction<'a, T: TreeTypes, V> { /* private fields */ }

Implementations

impl<'a, T: TreeTypes, V> StreamTransaction<'a, T, V>

pub fn commit(self)

Methods from Deref<Target = StreamBuilder<T, V>>

pub fn snapshot(&self) -> Tree<T, V>

pub fn link(&self) -> Option<T::Link>

pub fn as_index_ref(&self) -> Option<&Index<T>>

pub fn level(&self) -> i32

pub fn is_empty(&self) -> bool

true for an empty tree

pub fn count(&self) -> u64

number of elements in the tree

pub fn root(&self) -> Option<&T::Link>

root of a non-empty tree

pub fn index(&self) -> Option<&Index<T>>

root of a non-empty tree

pub fn transaction(&mut self) -> StreamTransaction<'_, T, V>

Modify a StreamBuilder and roll back the changes if the operation was not successful

Note that consumed offets are not rolled back to make sure we don’t reuse offsets.
