Enum JcsError 

#[non_exhaustive]
pub enum JcsError {
    NonFiniteNumber,
    DuplicateKey(String),
    Serde(Error),
}

Errors that can occur during canonicalization.

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.

NonFiniteNumber

JSON contained a non-finite number (NaN or Infinity); RFC 8785 forbids these.

DuplicateKey(String)

Reserved. Duplicate object keys are not detected here: this module canonicalizes an already-parsed serde_json::Value, and serde_json (built with preserve_order) collapses duplicate keys last-wins at parse time, before canonicalization. Since both signer and verifier canonicalize the same parsed value, there is no signature split-brain (RFC 8785 operates on parsed JSON). This variant is retained for API stability and is never constructed by canonicalize; reject duplicate keys at a raw-bytes deserialization step if a deployment’s threat model requires it.

Serde(Error)

Underlying serde error.

Trait Implementations

impl Debug for JcsError

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

Formats the value using the given formatter.

impl Display for JcsError

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

Formats the value using the given formatter.

impl Error for JcsError

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 JcsError

fn from(source: Error) -> Self

Converts to this type from the input type.
