Trait Implementations

impl Clone for MemStorage

fn clone(&self) -> MemStorage

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for MemStorage

fn default() -> MemStorage

Returns the “default value” for a type.

impl Storage for MemStorage

fn append(&self, file: &str, chunk: &[u8]) -> Result<()>

appends to a file. Should only return when the data is safely on disk (flushed)! appending will usually be done in large chunks. appending to a non existing file creates it. appending an empty chunk is a noop.

fn load(&self, file: &str, f: Box<dyn FnMut(&[u8])>) -> Result<()>

load a file. The callback will get to look at the data and do something with it. loading a non-existing file is like loading an empty file. It will not create the file.

fn mv(&self, from: &str, to: &str) -> Result<()>

atomically move a file. target will be atomically overwritten. if the source file does not exist, the target file will be deleted.
