pub enum PoswError {
    Parameters(ParametersError),
    PoswVerificationFailed,
    SnarkError(SNARKError),
    IoError(IoError),
    ConstraintFieldError(ConstraintFieldError),
}

An error when generating/verifying a Proof of Succinct Work

Variants

Parameters(ParametersError)

Thrown when the parameters cannot be loaded

PoswVerificationFailed

Thrown when a proof fails verification

SnarkError(SNARKError)

Thrown when there's an internal error in the underlying SNARK

IoError(IoError)

Thrown when there's an IO error

ConstraintFieldError(ConstraintFieldError)

Thrown if the mask conversion to a field element fails

Trait Implementations

impl Debug for PoswError

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

Formats the value using the given formatter.

impl Display for PoswError

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

Formats the value using the given formatter.

impl Error for PoswError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
