Writes a proving key to a buffer.
Writes a curve element according to format
:
Processed
: Writes a compressed curve element with coordinates in standard form. Writes a field element in standard form, with endianness specified by thePrimeField
implementation.- Otherwise: Writes an uncompressed curve element with coordinates in Montgomery form Writes a field element into raw bytes in its internal Montgomery representation, WITHOUT performing the expensive Montgomery reduction. Does so by first writing the verifying key and then serializing the rest of the data (in the form of field polynomials)

reader: &mut R,

pub fn read<R, ConcreteCircuit>( reader: &mut R, format: SerdeFormat, params: <ConcreteCircuit as Circuit<<C as PrimeCurveAffine>::Scalar>>::Params, ) -> Result<ProvingKey<C>, Error>
Reads a proving key from a buffer. Does so by reading verification key first, and then deserializing the rest of the file into the remaining proving key data.
Reads a curve element from the buffer and parses it according to the format
:
Processed
: Reads a compressed curve element and decompresses it. Reads a field element in standard form, with endianness specified by thePrimeField
implementation, and checks that the element is less than the modulus.RawBytes
: Reads an uncompressed curve element with coordinates in Montgomery form. Checks that field elements are less than modulus, and then checks that the point is on the curve.RawBytesUnchecked
: Reads an uncompressed curve element with coordinates in Montgomery form; does not perform any checks
