/// \module uctypes - Access data structures in memory
///
/// The module allows to define layout of raw data structure (using terms
/// of C language), and then access memory buffers using this definition.
/// The module also provides convenience functions to access memory buffers
/// contained in Python objects or wrap memory buffers in Python objects.
/// \constant UINT8_1 - uint8_t value type
/// \class struct - C-like structure
///
/// Encapsulalation of in-memory data structure. This class doesn't define
/// any methods, only attribute access (for structure fields) and
/// indexing (for pointer and array fields).
///
/// Usage:
///
/// # Define layout of a structure with 2 fields
/// # 0 and 4 are byte offsets of fields from the beginning of struct
/// # they are logically ORed with field type
/// FOO_STRUCT = {"a": 0 | uctypes.UINT32, "b": 4 | uctypes.UINT8}
///
/// # Example memory buffer to access (contained in bytes object)
/// buf = b"\x64\0\0\0\0x14"
///
/// # Create structure object referring to address of
/// # the data in the buffer above
/// s = uctypes.struct(FOO_STRUCT, uctypes.addressof(buf))
///
/// # Access fields
/// print(s.a, s.b)
/// # Result:
/// # 100, 20
