Implementations

impl ZoneTxn<'_>

pub fn read(&self, name: &str) -> Result<Option<Vec<u8>>, StoreError>

A file’s whole content as committed, or None if it doesn’t exist.

pub fn put(&mut self, name: &str, data: &[u8]) -> Result<(), StoreError>

Replace a file’s content, creating the file if it doesn’t exist.

pub fn put_if_absent( &mut self, name: &str, data: &[u8], ) -> Result<bool, StoreError>

Create a file with data unless it already exists; true if it was created. For content-addressed files, whose content never changes.

pub fn append_lines( &mut self, name: &str, data: &[u8], ) -> Result<(), StoreError>

Append complete \n-terminated lines, creating the file if needed.

fn ensure(&self, name: &str) -> Result<(), StoreError>

fn touch(&mut self, name: &str)
