Why a mount could not be added.

Variants

RootDisabled

The VFS has no root directory to mount below (vfs: none).

BadPath(String)

The guest path is not an absolute, normalized path.

AtRoot

/ is the root itself.

ProtectedPath(String)

The guest path names Git metadata.

Nested

One mount would sit inside another.

Fields

outer: String

inner: String

DuplicateVolume

The same volume is already mounted, or backs the root.

Fields

volume: String

at: String

TooMany

MountPointUnavailable

The mount point exists in the root but is not a plain directory, or does not exist in a read-only root, which it may not create.

Fields

path: String

reason: &'static str

RootIo(Error)

Preparing the mount point in the root failed.

Io(Error)

Opening the volume’s directory failed. Carries no host path; the caller logs that.

Trait Implementations

impl Debug for MountError

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

Formats the value using the given formatter.

impl Display for MountError

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

Formats the value using the given formatter.

impl Error for MountError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
