Errors that can occur during CASC operations.

Variants

Io(Error)

An underlying I/O failure (file not found, permission denied, etc.).

InvalidMagic

File magic bytes do not match the expected format identifier.

Fields

expected: String

The magic bytes the parser expected (e.g. "BLTE", "EN").

found: String

The magic bytes actually found in the data.

InvalidFormat(String)

Structural parse failure - truncated data, bad field values, or unexpected layout.

KeyNotFound

A referenced key was not found in the index, encoding table, or root file.

Fields

key_type: String

The kind of key that was looked up (e.g. "EKey", "CKey").

hash: String

Hex representation of the key that was not found.

UnsupportedVersion(u32)

The file format version is not supported by this library.

EncryptionKeyMissing(String)

A TACT encryption key is required but was not present in the key store.

DecompressionFailed(String)

Zlib or LZ4 decompression failed.

ChecksumMismatch

Content hash does not match the expected value after extraction.

Fields

expected: String

The expected hash (from the encoding or root table).

actual: String

The hash computed from the extracted data.

Http(Error)

A network request failed (e.g. listfile download).

Trait Implementations

impl Debug for CascError

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

Formats the value using the given formatter.

impl Display for CascError

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

Formats the value using the given formatter.

impl Error for CascError

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 CascError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for CascError

fn from(source: Error) -> Self

Converts to this type from the input type.
