Previously,
PublicKey::pointandSignature::pointconverted the underlyingFixedVector<u8, N>into aVec<u8>on every call just to feed compressed bytes intoG1Affine::from_compressed/G2Affine::from_compressed. This added unnecessary heap allocations and copies on the hot path of BLS signature verification. This change updates both helpers to borrow the bytes directly from theFixedVectorvia a slice and convert that slice into the fixed-size array expected byfrom_compressed, keeping behavior identical while eliminating the extra allocations.
