A set of templated constants to determine limits of integral types at compile time.

Member constants

min The minimum value the type can hold.
max The maximum value the type can hold.
bits The number of bits used for this type.
is_signed Whether the type is signed.

Example

template <const size_t SIZE>
struct Value
{
  etl::array<T, SIZE> data;
};

template <typename T>
void foo(const Value<etl::integral_limits<T>::bits>& value)
{
  size_t size = value.data.size(); // Same as the number of bits that represent a T
}
