Enum dcaf::error::CoseCipherError

#[non_exhaustive]
pub enum CoseCipherError<T> where
    T: Display,  {
    HeaderAlreadySet {
        existing_header_name: String,
    },
    VerificationFailure,
    DecryptionFailure,
    Other(T),
}

Error type used when a CoseEncrypt0Cipher, CoseSign1Cipher, or CoseMac0Cipher. fails to perform an operation.

T is the type of the nested error represented by the Other variant.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

HeaderAlreadySet

Fields

existing_header_name: String

The name of the header which has already been set.

A header which the cipher is supposed to set has already been set.

VerificationFailure

The given signature or MAC tag is either invalid or does not match the given data.

DecryptionFailure

The given ciphertext could not be decrypted.

Other(T)

A different error has occurred. Details are provided in the contained error.

Implementations

impl<T> CoseCipherError<T> where
    T: Display, 

pub fn existing_header_label(label: &Label) -> CoseCipherError<T>

Creates a new CoseCipherError of type HeaderAlreadySet where the header that was already set has the name of the given label.

pub fn existing_header<S>(name: S) -> CoseCipherError<T> where
    S: Into<String>, 

Creates a new CoseCipherError of type HeaderAlreadySet where the header that was already set has the given name.

pub fn other_error(other: T) -> CoseCipherError<T>

Creates a new CoseCipherError of type Other (i.e., an error type that doesn’t fit any other CoseCipherError variant) containing the given nested error other.

Trait Implementations

impl<T: Clone> Clone for CoseCipherError<T> where
    T: Display, 

fn clone(&self) -> CoseCipherError<T>

Returns a copy of the value.

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
