Enum OpenError 

#[non_exhaustive]
pub enum OpenError {
    InvalidBlockSize,
    ParseInodeFailed {
        source: FromRawError,
    },
    ReadBlockFailed {
        block: u32,
        source: Error,
    },
    InvalidSuperRoot,
    LoadBlockMapFailed {
        inode: usize,
        source: LoadBlocksError,
    },
}

Shared errors for PFS open operations.

These errors can occur in both open_slice() and open_image() during the common phase: validating the header, reading inodes, and precomputing block maps.

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.

Trait Implementations

impl Debug for OpenError

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

Formats the value using the given formatter.

impl Display for OpenError

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

Formats the value using the given formatter.

impl Error for OpenError

where Self: Debug + Display,

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

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

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 ErrorCompat for OpenError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<OpenError> for OpenImageError

fn from(error: OpenError) -> Self

Converts to this type from the input type.

impl From<OpenError> for OpenSliceError

fn from(error: OpenError) -> Self

Converts to this type from the input type.
