ZTL is an acronym for ZIMO template library, a conglomerate of utilities specifically for embedded systems. It currently contains the following headers:

• bits.hpp
  Various constexpr functions for bitmasking things

• compilation_time.hpp
  Compiletime stamps from __DATE__ and __TIME__ macros

• counted_latch.hpp
  Latches it's value after it hasn't changed for at least I times

• delayed_latch.hpp
  Latches it's value after is hasn't changed for at least I ticks

• cstring.hpp
  Stack allocated container for string

• directional_latch.hpp
  Latches it's value after it hasn't changed direction for at least I times

• edge_detector.hpp
  Detects rising and falling edges

• enum.hpp
  Operator overloads for enum classes enabled by specializing a struct

• explicit_wrapper.hpp
  Value wrapper without any implicit conversions

• fail.hpp
  Delays a static_assert failure till instantiation (and can therefor be used in constexpr context)

• fixed_string.hpp
  Constexpr string class with user-defined literal

• implicit_wrapper.hpp
  Like explicit_wrapper, but allows implicit conversions back to its underlying type

• inplace_deque.hpp
  Stack allocated double-ended queue which push- and pop functions for front and back

• inplace_list.hpp Stack allocated double-linked list with random insert / erase and push- / pop functions for front and back

• inplace_vector.hpp
  Incomplete implementation of std::inplace_vector proposal P0843r6

• limits.hpp
  Minimal representation of signed- or unsigned integral types within given interval

• math.hpp
  Constexpr versions of various algorithms

• meta.hpp
  Minimal set of useful constexpr algorithms

• moving_average.hpp
  Moving average class with specified window size

• overload.hpp
  Creates overload set by inheriting from passed lambdas or functors

• spline.hpp
  Hermite spline implementation

• static_list.hpp
  Doubly linked list which manages externally created nodes

• string.hpp
  Constexpr implementations of atoi, strcmp, strlen

• system_error.hpp
  Basically std::error_code without enforcing inheritance of std::error_category

• type_traits.hpp
  Many non-standard additions to <type_traits>

• units.hpp
  User-defined literals for some physical units (e.g. Hz or ms)

• utility.hpp
  Variable templates and operator overloads for std::integral_constant and make_index_sequence_from_to
