Enum MountError 

pub enum MountError {
    NotFound(String),
    Stale(String),
    NotADirectory(String),
    UnknownThread(String),
    ReadOnly,
    Store(HeddleError),
}

Errors surfaced by the content-addressed mount core.

Variants

NotFound(String)

The requested path or node does not exist in the current state.

Stale(String)

The node referenced by the caller is no longer valid (stale inode, invalidated cache, etc).

NotADirectory(String)

A path component traversed something that wasn’t a directory.

UnknownThread(String)

The thread name does not resolve to a current state.

ReadOnly

Read-only filesystem (used while overlay-write is stubbed).

Store(HeddleError)

Errors bubbling up from the underlying object store / repo.

Implementations

impl MountError

pub fn to_errno(&self) -> i32

Translate this error into a libc errno suitable for handing back to FUSE. Only the platform shell uses this — keeping it here means platform code stays one-liners.

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, __formatter: &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.

impl From<HeddleError> for MountError

fn from(source: HeddleError) -> Self

Converts to this type from the input type.
