sourcepub fn write<W: Write>(&self, writer: &mut W, format: SerdeFormat) -> Result<()>
pub fn write<W: Write>(&self, writer: &mut W, format: SerdeFormat) -> Result<()>
Writes a verifying 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.
sourcepub fn read<R: Read>(
reader: &mut R,
format: SerdeFormat,
cs: ConstraintSystemBack<C::Scalar>
) -> Result<Self>
pub fn read<R: Read>( reader: &mut R, format: SerdeFormat, cs: ConstraintSystemBack<C::Scalar> ) -> Result<Self>
Reads a verification key from a buffer.
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
