Every way an argument to this layer can be refused.

Closed, and each arm reads differently, so a reader of the raised message is sent to the one thing that was wrong.

Variants

NotHexText

A key or signature argument that is not a string at all.

Fields

what: &'static str

got: &'static str

NotHex

A character outside 0-9a-fA-F, at a character position.

Fields

what: &'static str

position: usize

found: char

OddHex

An odd number of hex digits cannot be whole bytes.

Fields

what: &'static str

digits: usize

WrongLength

Well-formed hex of the wrong size.

Fields

what: &'static str

expected: usize

got: usize

NotAMessage

Something that is neither text nor a byte list.

Fields

got: &'static str

NotAByte

A byte-list element that is not an integer.

Fields

index: usize

got: &'static str

ByteOutOfRange

A byte-list element outside 0..=255.

Fields

index: usize

value: i64

NotACurvePoint

32 bytes that do not decompress to a point on the curve.

WeakPublicKey

A point of small order: every signature under it is meaningless.

NotAnAlgorithm

Fields

got: &'static str

UnknownAlgorithm

Fields

name: String

NoMac

Fields

name: &'static str

known: &'static str

BadMacKey

Trait Implementations

impl Clone for CryptoError

fn clone(&self) -> Self

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, __formatter: &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: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.
