Constructors

• .from_be_bytes(bytes : Bytes) : UInt64

  Create a UInt64 value from its representation as a byte array in big endian.

• .from_bytes(bytes : Bytes, format : IO::ByteFormat = IO::ByteFormat::SystemEndian) : UInt64

  Create a UInt64 value from its representation as a byte array.

• .from_le_bytes(bytes : Bytes) : UInt64

  Create a UInt64 value from its representation as a byte array in little endian.

Instance Method Summary

• #to_be_bytes : Bytes

  Return the memory representation of this number as a byte array in big-endian (network) byte order.

• #to_bytes(format : IO::ByteFormat = IO::ByteFormat::SystemEndian) : Bytes

  Return the memory representation of this number as a byte array using the specified format

• #to_le_bytes : Bytes

  Return the memory representation of this number as a byte array in little-endian byte order.
