Struct ServingVolume

pub struct ServingVolume { /* private fields */ }

Represents an opened volume in a [`ServingMultiVolumeFilesystem’] instance.

Implementations

impl ServingVolume

pub fn root(&self) -> &DirectoryProxy

Returns a proxy to the root directory of the serving volume.

pub fn exposed_dir(&self) -> &DirectoryProxy

Returns a proxy to the exposed directory of the serving volume.

pub fn bind_to_path(&mut self, path: &str) -> Result<(), Error>

Binds the root directory being served by this filesystem to a path in the local namespace. The path must be absolute, containing no “.” nor “..” entries. The binding will be dropped when self is dropped, or when unbind_path is called. Only one binding is supported.

Errors

Returns Err if binding failed, or if a binding already exists.

pub fn unbind_path(&mut self)

Remove the namespace binding to the root directory being served by this volume, if there is one. If there is no binding, this function does nothing. After this, it is safe to call bind_to_path again.

pub fn bound_path(&self) -> Option<&str>

pub async fn query(&self) -> Result<Box<FilesystemInfo>, QueryError>

Returns a [FilesystemInfo] object containing information about the serving volume.

Errors

Returns Err if querying the filesystem failed.
