Enum pairing_plus::GroupDecodingError

pub enum GroupDecodingError {
    NotOnCurve,
    NotInSubgroup,
    CoordinateDecodingError(&'static str, PrimeFieldDecodingError),
    UnexpectedCompressionMode,
    UnexpectedInformation,
}

An error that may occur when trying to decode an EncodedPoint.

Variants

NotOnCurve

The coordinate(s) do not lie on the curve.

NotInSubgroup

The element is not part of the r-order subgroup.

CoordinateDecodingError(&'static str, PrimeFieldDecodingError)

One of the coordinates could not be decoded

UnexpectedCompressionMode

The compression mode of the encoded element was not as expected

UnexpectedInformation

The encoding contained bits that should not have been set

Trait Implementations

impl Debug for GroupDecodingError

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

Formats the value using the given formatter.

impl Display for GroupDecodingError

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

Formats the value using the given formatter.

impl Error for GroupDecodingError

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
