Enum SignatureError 

#[non_exhaustive]
pub enum SignatureError {
    InvalidFormat,
    Mismatch,
    TimestampExpired,
    MissingTimestamp,
    Crypto(String),
}

Errors produced by low-level signature verification routines.

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.

InvalidFormat

The signature header value could not be parsed according to the provider’s expected format. For example, a GitHub signature missing the sha256= prefix triggers this variant.

Mismatch

The computed signature did not match the value supplied in the request header.

TimestampExpired

The timestamp embedded in the request is older than the configured tolerance window, indicating a potential replay attack.

MissingTimestamp

A timestamp is required for this provider’s signing scheme but was not found in the request.

Crypto(String)

A cryptographic operation failed (e.g., an invalid key was supplied or key parsing failed). The inner string contains the underlying error message.

Trait Implementations

impl Debug for SignatureError

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

Formats the value using the given formatter.

impl Display for SignatureError

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

Formats the value using the given formatter.

impl Error for SignatureError

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.
