Struct NumAppender

pub struct NumAppender<T, const N: u32>(pub Option<T>);

An integer appender.

When T implements Default, AddAssign<T> and MulAssign<usize> then NumAppender<T, N> implements Appender<T> in the following way: if self contains t of type T then pushing s in self updates t into (t * N) + s.

This struct is useful when you want to parse an integer from a text file.
