    ExpiredToken(String),

Error returned when an attempt at validating an AWS SigV4 signature fails.

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.

ExpiredToken(String)

The security token included with the request is expired.

IO(Error)

Validation failed due to an underlying I/O error.

InternalServiceError(Box<dyn Error + Send + Sync>)

Validation failed due to an internal service error.

InvalidBodyEncoding(String)

The request body used an unsupported character set encoding. Currently only UTF-8 is supported.

InvalidClientTokenId(String)

The AWS access key provided does not exist in our records.

InvalidContentType(String)

The content-type of the request is unsupported.

InvalidRequestMethod(String)

Invalid request method.

IncompleteSignature(String)

The request signature does not conform to AWS standards. Sample messages:
Authorization header requires 'Credential' parameter. Authorization=...
Authorization header requires existence of either a 'X-Amz-Date' or a 'Date' header.
Date must be in ISO-8601 'basic format'. Got '...'. See http://en.wikipedia.org/wiki/ISO_8601
Unsupported AWS 'algorithm': 'AWS4-HMAC-SHA512'

InvalidURIPath(String)

The URI path includes invalid components. This can be a malformed hex encoding (e.g. %0J), a non-absolute URI path (foo/bar), or a URI path that attempts to navigate above the root (/x/../../../y).

MalformedQueryString(String)

A query parameter was malformed – the value could not be decoded as UTF-8, or the parameter was empty and this is not allowed (e.g. a signature parameter), or the parameter could not be parsed (e.g., the X-Amz-Date parameter is not a valid date).

Incomplete trailing escape % sequence

MissingAuthenticationToken(String)

The request must contain either a valid (registered) AWS access key ID or X.509 certificate. Sample messages:
Request is missing Authentication Token

SignatureDoesNotMatch(Option<String>)

Signature did not match the calculated signature value. Example messages:
The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.
Signature expired: 20210502T144040Z is now earlier than 20210502T173143Z (20210502T174643Z - 15 min.)
Signature not yet current: 20210502T183640Z is still later than 20210502T175140Z (20210502T173640Z + 15 min.)

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, f: &mut Formatter<'_>) -> FmtResult

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.

fn from(e: Box<dyn Error + Send + Sync>) -> SignatureError

Converts to this type from the input type.

impl From<Error> for SignatureError

fn from(e: IOError) -> SignatureError

Converts to this type from the input type.

impl ServiceError for SignatureError
