Struct cfgrammar::TIdx

pub struct TIdx<T>(pub T);

A type specifically for token indices.

It is guaranteed that TIdx can be converted, without loss of precision, to usize with the idiom TIdx::from(x_usize). usize values can be converted to TIdx, causing a panic if this would lead to a loss of precision with usize::from(y_tidx).
