Trait TileStore

    // Required methods

    // Provided method
    fn exists(&self, path: &str) -> Result<bool> { ... }
}

Byte storage keyed by store path.

Required Methods

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.

Provided Methods

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

Whether anything is stored at path.
