Utility namespace.

Classes

template <typename IntType> struct BytePacker: Object for packing and unpacking bytes as integers.

enum class Endianness { BigEndian, LittleEndian }: Enum class to represent byte order.

template <class SizedRange1, class SizedRange2> auto concatBytes(SizedRange1 const& r1, SizedRange2 const& r2) → auto: Concatenate two byte ranges.
template <std::size_t N> auto makeByteArray(std::span<const uint8_t> vec) → std::array< uint8_t, N > -> auto constexpr: Convert a span of bytes into a fixed size array.
auto rationalApprox(double f, int64_t md) → std::pair< int64_t, int64_t > -> auto: Approximate a floating point number as a rational number.
void writeEnvelopeTextFile(const std::string_view file_path, const std::string_view type, const std::string_view description, const std::string_view cbor_hex): Write CBOR date to file in the envelope format used by cardano node.

Concatenate two byte ranges.

Returns	A vector containing the elements of both ranges.

Convert a span of bytes into a fixed size array.

Returns	An array containing the elements from the input.

Approximate a floating point number as a rational number.

Parameters
f	The floating point number to convert.
md	The maximum denominator.
Returns	The numerator and denominator as a pair of integers.

Write CBOR date to file in the envelope format used by cardano node.

Parameters
file_path	Path to the generated key file.
type	A string key type specifier.
description	Description of the key (maybe empty).
cbor_hex	The CBOR key data in hex string format.
