std::num::NonZero* IDL build is failed

[hrls]

#[program]
pub mod unzero {
    use super::*;

    pub fn initialize(ctx: Context<Initialize>, value: std::num::NonZeroU64) -> Result<()> {
        Ok(())
    }
}

anchor idl build output is below:

I'm not sure anchor provides a serializer for it. You could write a wrapper:

impl NonZeroWrapper {
    pub fn get(&self) -> Option<std::num::NonZeroU64> {
        std::num::NonZeroU64::new(self.0)
    }
}

and use it instead

Yes, it looks like anchor has no serializer.
IMO std-based type should be supported in native way without making boilerplate wrappers.
