Enum PolicyBindingError 

#[non_exhaustive]
pub enum PolicyBindingError {
    UnsupportedAlgorithm {
        alg: String,
    },
    EmptyHash,
    InvalidBase64(DecodeError),
    InvalidHashLength {
        actual: usize,
    },
    InvalidHexHash,
}

Why PolicyBinding::validate rejected a policy binding.

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.

UnsupportedAlgorithm

alg is not a recognized policy binding algorithm (only HS256 is).

Fields

alg: String

The alg value found in the binding.

EmptyHash

hash is the empty string.

InvalidBase64(DecodeError)

hash is not padded standard-alphabet base64.

InvalidHashLength

hash is base64, but of neither a 32-byte HMAC-SHA256 nor its 64-character hex encoding.

Fields

actual: usize

Number of bytes hash decoded to.

InvalidHexHash

hash decodes to 64 bytes that are not all hexadecimal digits, so it is not the legacy Base64(hex(HMAC-SHA256)) form.

Trait Implementations

impl Clone for PolicyBindingError

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 PolicyBindingError

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

Formats the value using the given formatter.

impl Display for PolicyBindingError

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

Formats the value using the given formatter.

impl Eq for PolicyBindingError

impl Error for PolicyBindingError

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<DecodeError> for PolicyBindingError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl PartialEq for PolicyBindingError

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

Equality operator ==.

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

Inequality operator !=.
