Struct k256::ecdsa::recoverable::Id

pub struct Id(_);

Identifier used to compute a VerifyingKey from a Signature.

In practice these values are always either 0 or 1, and indicate whether or not the y-coordinate of the original VerifyingKey is odd.

While values 2 and 3 are also defined to capture whether r overflowed the curve’s order, this crate does not support them.

There is a vanishingly small chance of these values occurring outside of contrived examples, so for simplicity’s sake handling these values is unsupported and will return an Error when parsing the Id.
