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.

Style

Based on Google C++ Style.
Informed by C++ Core Guidelines.

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 #undefed.

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.
