Enum DiscoverError 

#[non_exhaustive]
pub enum DiscoverError {
    PointerUnreadable(PathBuf, Error),
    PointerMalformed(PathBuf),
    PointerTooLarge(PathBuf),
    PointerSymlink(PathBuf),
    StateDirMissing(PathBuf),
    CommonDirUnreadable(PathBuf, Error),
    CommonDirMissing(PathBuf),
}

Errors surfaced by discover on a broken linked-worktree setup.

A repository whose .mkit is a directory (every single-worktree repository) can never produce one of these — discovery only engages the fail-closed path once .mkit is a pointer FILE.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PointerMalformed(PathBuf)

Trait Implementations

impl Debug for DiscoverError

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

Formats the value using the given formatter.

impl Display for DiscoverError

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

Formats the value using the given formatter.

impl Error for DiscoverError

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<DiscoverError> for GcRootsError

fn from(source: DiscoverError) -> Self

Converts to this type from the input type.
