## What is Magic Enum?
Header-only C++17 library provides Enum-to-String and String-to-Enum functions.
* `magic_enum::enum_to_string` obtains string enum name from enum variable.
* `magic_enum::enum_from_string` obtains enum variable from enum string name.
* `magic_enum::enum_from_string` obtains enum value from enum string name.
* `magic_enum::enum_to_sequence` obtains value enum sequence.
* `magic_enum::enum_to_string_sequence` obtains string enum name sequence.
## Features

* Enum to value sequence
```cpp
constexpr auto colors = magic_enum::enum_to_sequence<Color>();
// colors -> {Color::RED, Color::BLUE, Color::GREEN}
```
* Enum to string enum name sequence
```cpp
constexpr auto color_names = magic_enum::enum_to_string_sequence<Color>();
// color_names -> {"RED", "BLUE", "GREEN"}
```
## Remarks
* `magic_enum::enum_to_string` returns `std::optional<std::string_view>`, using `has_value()` to check contains enum name and `value()` to get the enum name. If enum variable does not have name or out of range `MAGIC_ENUM_RANGE`, returns `std::nullopt`.
* `magic_enum::enum_to_string` returns `std::optional<std::string_view>`, using `has_value()` to check contains enum name and `value()` to get the enum name. If enum value does not have name or out of range `MAGIC_ENUM_RANGE`, returns `std::nullopt`.
* `magic_enum::enum_from_string` returns `std::optional<E>`, using `has_value()` to check contains enum variable and `value()` to get the enum variable. If enum variable does not have name or out of range `MAGIC_ENUM_RANGE`, returns `std::nullopt`.
* `magic_enum::enum_from_string` returns `std::optional<E>`, using `has_value()` to check contains enum value and `value()` to get the enum value. If enum value does not have name or out of range `MAGIC_ENUM_RANGE`, returns `std::nullopt`.
* Enum variable must be in range `(-MAGIC_ENUM_RANGE, MAGIC_ENUM_RANGE)`. By default `MAGIC_ENUM_RANGE = 128`. If you need larger range, redefine the macro `MAGIC_ENUM_RANGE`.
* `magic_enum::enum_to_sequence` returns `std::array<E, N>` with all value enum, sorted by enum value.
* `magic_enum::enum_to_string_sequence` returns `std::array<std::string_view, N>` with all string enum name, sorted by enum value.
* Enum value must be in range `(-MAGIC_ENUM_RANGE, MAGIC_ENUM_RANGE)`. By default `MAGIC_ENUM_RANGE = 128`. If you need larger range, redefine the macro `MAGIC_ENUM_RANGE`.
