Enum pairing::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
