Reasons a SigV4 verification can fail. Each variant maps onto the AWS-shape error the caller should return.

Variants

RequestTimeTooSkewed

Request was signed more than 15 minutes from the server’s clock. Maps to AWS RequestTimeTooSkewed.

Fields

signed: DateTime<Utc>

server: DateTime<Utc>

Malformed(&'static str)

Authorization header or presigned URL was not a well-formed AWS4-HMAC-SHA256 signature. Maps to AWS IncompleteSignature or InvalidSignatureException.

SignatureMismatch

The computed signature did not match the signature the client sent. Maps to AWS SignatureDoesNotMatch.

InvalidDate(&'static str)

X-Amz-Date / credential-scope date could not be parsed.

PresignedUrlExpired

Presigned URL is past its X-Amz-Expires lifetime. Maps to AWS AccessDenied (“Request has expired”).

Fields

signed: DateTime<Utc>

server: DateTime<Utc>

expires_secs: i64

InvalidPresignExpires(i64)

Presigned X-Amz-Expires was absent or outside the 1..=604800 range.

Trait Implementations

impl Debug for SigV4Error

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

Formats the value using the given formatter.

impl Display for SigV4Error

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

Formats the value using the given formatter.

impl Error for SigV4Error

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.
