Enum CryptoError 

pub enum CryptoError {
    InvalidKey,
    InvalidNonce,
    InvalidTag,
    BufferTooSmall,
    BadInput,
    Internal(&'static str),
    Kex,
    Sign,
    Rng,
    Encoding,
    UnsupportedAlgorithm,
}

Unified error type for all OxiCrypto operations.

Variants

InvalidKey

Supplied key has wrong length or is otherwise invalid.

InvalidNonce

Supplied nonce/IV has wrong length or is otherwise invalid.

InvalidTag

Authentication tag verification failed (AEAD open / MAC verify).

BufferTooSmall

Output buffer is too small for the requested operation.

BadInput

General bad-input condition (e.g. zero-length KDF output requested).

Internal(&'static str)

An internal or backend error with a static message.

Serde note: When deserializing, the &'static str payload cannot be reconstructed from arbitrary data in a no_std + alloc crate. The variant is deserialized as Internal("") — the serialized form preserves the string for observability/logging; round-trip lossiness is intentional.

Kex

Key-exchange or encapsulation/decapsulation failure (e.g. ML-KEM).

Sign

Signature generation or verification failure (e.g. ML-DSA).

Rng

RNG-specific failure (e.g. getrandom unavailable).

Encoding

Encoding / decoding failure (DER, PEM, SEC1, etc.).

UnsupportedAlgorithm

Requested algorithm is not compiled-in or not supported at runtime.

Trait Implementations

impl Clone for CryptoError

fn clone(&self) -> CryptoError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CryptoError

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

Formats the value using the given formatter.

impl Display for CryptoError

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

Formats the value using the given formatter.

impl Eq for CryptoError

impl Error for CryptoError

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 PartialEq for CryptoError

fn eq(&self, other: &CryptoError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
