Struct ZonbiId 

pub struct ZonbiId(/* private fields */);

A ZonbiId represents a globally unique identifier for the 'static version of a type.

Because ZonbiId relies on rust’s TypeId, please keep their warning in mind that the hashes and ordering will vary between Rust releases. Beware of relying on them inside of your code!

Implementations

impl ZonbiId

pub fn of<'life, Z: Zonbi<'life>>() -> ZonbiId

Returns the ZonbiId of the given generic type.

This is equal to the TypeId of the 'static version of the type.

fn with_zonbi<'a>(a: &'a NonCopyI32) {
    let my_struct = MyStruct { val: a };
