Struct SigningError 

pub struct SigningError(/* private fields */);

Represents an error occurred during a signing operation.

This error can occur when using a Signer to sign content. It may represent a transport error when using a remote API (like the IAM signBlob API) or a parsing/signing error when performing local signing with a service account key.

Applications rarely need to create instances of this error type. The exception might be when testing application code, where the application is mocking a Signer behavior.

Example

let content = b"content to sign";
match signer.sign(content).await {
    Ok(signature) => println!("Signature: {:?}", signature),
    Err(e) if e.is_transport() => println!("Transport error: {}", e),
    Err(e) => println!("Other error: {}", e),
}

Implementations

impl SigningError

pub fn is_transport(&self) -> bool

Returns true if the error was caused by a transport problem.

This typically happens when using a remote signer (like the IAM signBlob API) and the network request fails or the service returns a transient error.

pub fn is_parsing(&self) -> bool

Returns true if the error was caused by a parsing problem.

This typically happens when the signer is using a private key that cannot be parsed or is invalid.

pub fn is_sign(&self) -> bool

Returns true if the error was caused by a problem during the signing operation.

This can happen during local signing if the cryptographic operation fails, or if the remote API returns an error that is not a transport error.

Trait Implementations

impl Debug for SigningError

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

Formats the value using the given formatter.

impl Display for SigningError

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

Formats the value using the given formatter.

impl Error for SigningError

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.
