Variants

FileNotFound(String)

Binary file was not found at the specified path.

InvalidFileFormat

Binary file format is invalid or unrecognized.

InvalidFileFormatDetails(String)

Binary file format is invalid with specific details.

UnsupportedVersion(u8)

Binary file version is not supported.

HeaderChecksumMismatch

Header checksum verification failed.

DecryptionFailed

Decryption failed due to invalid key or corrupted data.

EncryptionFailed(String)

Encryption operation failed.

MachineIdUnavailable(String)

Machine ID could not be determined.

MachineMismatch

File is bound to a different machine.

SecretRequired

Operation requires a secret key but none was provided.

InvalidLength

Code has incorrect length.

Fields

expected: usize

Expected code length.

actual: usize

Actual code length.

InvalidCharacter(char)

Code contains a character not in the alphabet.

InvalidCheckDigit

Check digit verification failed.

CounterLocked

Counter file is locked by another process.

CounterOverflow

Counter has reached its maximum value.

Io(Error)

An I/O error occurred.

InvalidAlphabet(String)

The provided alphabet is invalid.

InvalidArgument(String)

An invalid argument was provided.

Json(Error)

JSON serialization or deserialization error.

Implementations

impl PromocryptError

pub fn code(&self) -> ErrorCode

Get the numeric error code for FFI and cross-component consistency.

Trait Implementations

impl Debug for PromocryptError

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

Formats the value using the given formatter.

impl Display for PromocryptError

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

Formats the value using the given formatter.

impl Error for PromocryptError

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 PromocryptError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for PromocryptError

fn from(source: Error) -> Self

Converts to this type from the input type.
