Struct MemoryStore 

pub struct MemoryStore { /* private fields */ }

Files in memory. Clones share the same files, so a writer and a reader can hold one store.

Implementations

impl MemoryStore

pub fn new() -> Self

An empty store.

pub fn total_bytes(&self) -> usize

Bytes stored, over every file.

pub fn bytes_under(&self, prefix: &str) -> usize

Bytes stored under prefix.

Trait Implementations

impl Clone for MemoryStore

fn clone(&self) -> MemoryStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MemoryStore

fn default() -> MemoryStore

Returns the “default value” for a type.

impl TileStore for MemoryStore

fn get(&self, path: &str) -> Result<Option<Vec<u8>>>

The bytes at path, or nothing when there is no such file.

fn put(&self, path: &str, bytes: &[u8]) -> Result<()>

Writes bytes at path, whole or not at all, replacing what is there.

fn create_new(&self, path: &str, bytes: &[u8]) -> Result<bool>

Writes bytes at path only when nothing is there; false when something is.

fn delete(&self, path: &str) -> Result<bool>

Removes path; false when there was nothing to remove.

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

Moves from to to, replacing what is at to.

fn list(&self, prefix: &str) -> Result<Vec<String>>

Every file path under prefix (a directory path without a trailing slash, or the empty string for the whole store), sorted.

fn exists(&self, path: &str) -> Result<bool>

Whether anything is stored at path.
