pub struct WriteSession<'a, S: Store> { /* private fields */ }

Bounded mutable view over an immutable base tree.

Implementations

impl<'a, S: Store> WriteSession<'a, S>

pub fn new(manager: &'a Prolly<S>, base: Tree, max_bytes: usize) -> Self

pub fn base(&self) -> &Tree

pub fn pending_bytes(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn put(&mut self, key: Vec<u8>, value: Vec<u8>) -> Result<(), Error>

pub fn delete(&mut self, key: Vec<u8>) -> Result<(), Error>

pub fn get(&self, key: &[u8]) -> Result<Option<Vec<u8>>, Error>

pub fn range( &self, start: &[u8], end: Option<&[u8]>, ) -> Result<Vec<KeyValue>, Error>

Materialize one bounded merged range from the base cursor and overlay.

pub fn savepoint(&self) -> Savepoint

pub fn revert(&mut self, savepoint: Savepoint) -> Result<(), Error>

pub fn flush(&mut self) -> Result<Tree, Error>

Flush through the canonical writer. State changes only after success.
