Enum group::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 Error for GroupDecodingError

fn description(&self) -> &str

This method is soft-deprecated.

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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

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 ocurred.
