Struct RequestId 

pub struct RequestId(pub u64);

Names one request for as long as its host tracks it.

Never reused, for the reason blitz-wasm gives for handles and listener ids: a stale id must be an error rather than a silent hit on whatever took its place. A guest that releases a request and then reads it gets FetchState::Unknown, not another request’s body.

A u64 here. A binding that has to return this to a guest through a negative-is-error i32 has a narrower range to work with, and capping it is that binding’s business, not this crate’s.
