Niche Optimization for Option<ReferenceId> and IndexVec<ReferenceId, T> #55
Description
we have these index types
where
can be trimmed by niche optimization.
But,
use std::num::NonZeroU32;
define_index_type! {
pub struct ReferenceId = NonZeroU32;
}is not supported by the macro define_index_type
error[E0599]: no function or associated item named `max_value` found for struct `NonZero` in the current scope

note: if you're trying to build a new `NonZero<u32>` consider using one of the following associated functions:
NonZero::<T>::new
NonZero::<T>::new_unchecked

but the good news is that we forked it and lives in https://github.com/oxc-project/oxc/tree/main/crates/oxc_index
The task of this issue is to make it work, if possible.
