Enum VssError 

pub enum VssError {
    Io(Error),
    StoreIndexOutOfRange {
        index: usize,
        count: usize,
    },
    StoreInfoUnavailable {
        index: usize,
    },
    StoreOffsetOutOfBounds {
        index: usize,
        offset: u64,
        volume_size: u64,
    },
}

An error decoding a Volume Shadow Copy volume.

The reader never panics on malformed input: out-of-range reads yield safe defaults through the bounds-checked helpers, and only genuine I/O failures or caller misuse (an out-of-range store index) surface as an error.

Variants

Io(Error)

An I/O error reading the underlying volume.

StoreIndexOutOfRange

A store index passed to crate::VssVolume::store_info is past the end of the enumerated stores.

Fields

index: usize

The requested index.

count: usize

The number of stores actually present.

StoreInfoUnavailable

The store has no catalog type-0x03 pointer, so its store-information block cannot be located (e.g. a Windows 2003 R2 catalog).

Fields

index: usize

The store index whose pointer is missing.

StoreOffsetOutOfBounds

A store-header offset read from the catalog runs past the end of the volume — consistent with a corrupt or tampered catalog entry.

Fields

index: usize

The store index whose pointer is out of range.

offset: u64

The offending offset.

volume_size: u64

The volume size the offset exceeded.

Trait Implementations

impl Debug for VssError

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

Formats the value using the given formatter.

impl Display for VssError

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

Formats the value using the given formatter.

impl Error for VssError

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<Error> for VssError

fn from(source: Error) -> Self

Converts to this type from the input type.
