# FTL
FTL is a template library shared by SurfaceFlinger and InputFlinger, inspired by
and supplementing the C++ Standard Library. The intent is to fill gaps for areas
not (yet) covered—like cache-efficient data structures and lock-free concurrency
primitives—and implement proposals that are missing or experimental in Android's
libc++ branch. The design takes some liberties with standard compliance, notably
assuming that exceptions are disabled.
## Tests
atest ftl_test
## Style
- Based on [Google C++ Style](https://google.github.io/styleguide/cppguide.html).
- Informed by [C++ Core Guidelines](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines).
Naming conventions are as follows:
- `PascalCase`
- Types and aliases, except standard interfaces.
- Template parameters, including non-type ones.
- `snake_case`
- Variables, and data members with trailing underscore.
- Functions, free and member alike.
- Type traits, with standard `_t` and `_v` suffixes.
- `kCamelCase`
- Enumerators and `constexpr` constants with static storage duration.
- `MACRO_CASE`
- Macros, with `FTL_` prefix unless `#undef`ed.
Template parameter packs are named with the following convention:
typename T, typename... Ts
typename Arg, typename... Args
std::size_t I, std::size_t... Is
std::size_t Size, std::size_t... Sizes
The `details` namespace contains implementation details.
