Struct ByteCache 

pub struct ByteCache { /* private fields */ }

Byte cache for liquid cache, act like a object store.

Implementations

impl ByteCache

pub fn new(inner: Arc<dyn ObjectStore>, cache_dir: PathBuf) -> Self

Create a new byte cache, the cache_dir is the directory to store the cached files ByteCache can read from a previously initialized cache directory

impl ObjectStore for ByteCache

fn list(&self, prefix: Option<&Path>) -> BoxStream<'static, Result<ObjectMeta>>
