## Traits

CurveAffine | Affine representation of an elliptic curve point guaranteed to be in the correct prime order subgroup. |

CurveProjective | Projective representation of an elliptic curve point guaranteed to be in the correct prime order subgroup. |

EncodedPoint | An encoded elliptic curve point, which should essentially wrap a |

Engine | An “engine” is a collection of types (fields, elliptic curve groups, etc.)
with well-defined relationships. In particular, the G1/G2 curve groups are
of prime order |

Field | This trait represents an element of a field. |

GenericRawEncodable | |

GenericUncompressedEncodable | |

PrimeField | This represents an element of a prime field. |

PrimeFieldRepr | This trait represents a wrapper around a biginteger which can encode any element of a particular
prime field. It is a smart wrapper around a sequence of |

RawEncodable | |

ScalarEngine | An “engine” is a collection of types (fields, elliptic curve groups, etc.) with well-defined relationships. Specific relationships (for example, a pairing-friendly curve) can be defined in a subtrait. |

SqrtField | This trait represents an element of a field that has a square root operation described for it. |
