Errors returned by StegoRust operations.

Variants

Io(Error)

An I/O error occurred.

Image(ImageError)

An image loading or saving error occurred.

InvalidConfig(String)

Invalid configuration parameter.

InvalidHeader

The header bytes are corrupt or the image is not a StegoRust carrier.

AuthenticationFailed

Decryption failed — wrong password or tampered image.

IntegrityCheckFailed

The reassembled payload hash does not match the stored hash.

InsufficientCapacity

Not enough pixel capacity in the cover images for the message.

Fields

needed: usize

Required bytes.

available: usize

Available bytes.

MissingChunks

The provided images do not supply all required chunks.

Fields

found: usize

Number of chunks found.

expected: usize

Number of chunks expected.

DuplicateChunk(u8)

A duplicate chunk index was encountered.

MixedMessages

Images from different messages were mixed together.

InvalidBitsPerChannel(u8)

bits_per_channel was outside the valid range 1–8.

Kdf(String)

Key derivation (Argon2 / HKDF) error.

Cipher(String)

Cipher (AES-GCM) error.

Trait Implementations

impl Debug for StegoError

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

Formats the value using the given formatter.

impl Display for StegoError

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

Formats the value using the given formatter.

impl Error for StegoError

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 StegoError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ImageError> for StegoError

fn from(source: ImageError) -> Self

Converts to this type from the input type.
