------------------------------------
Summary: [C++] C++14 laundry list
Key: ARROW-12816
URL: https://issues.apache.org/jira/browse/ARROW-12816
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Ben Kietzman
Improvements to make/be aware of once C++14 is available:
- Ensure that lambda closure members are moved into where ever
possible/appropriate. We have a lot of local variables whose only function is
getting copied into a closure, including some demotions to shared_ptr since
move only types can't be closed over in c++11
- visitor pattern can be used more fluidly with template lambdas, for example
we could have a utility like {{ VisitInts(offset_width, offset_bytes, [&](auto*
offsets) { /*mutate offsets*/ }) }}
- constexpr switch, for use in type traits functions
- std::enable_if_t
- std::quoted is available for quoting strings'
- std::make_unique
- standard {{[[deprecated]]}} attribute
- temporal literals such as ""s, ""ns, ...
- binary literals with place markers such as 0b1100_1111
