Detailed Description

Type-safe class for evdev codes (KEY_*, BTN_*, REL_*, etc).

A Code object can only be explicitly constructed from an integer. Conversion back to the integer value is implicit.

Member Typedef Documentation

BaseType

using BaseType = detail::NumberBase<std::uint16_t, Code>

value_type

using value_type = typename BaseType::Value

The underlying value, same as std::uint16_t.
