Trait ModStateHost 

pub trait ModStateHost {
    // Provided methods
    fn attachment_query(&self, namespace: &str, name: &str) -> AttachmentBatch { ... }
    fn attachments(&mut self) -> &mut dyn AttachmentStore { ... }
}

The host’s methods both sides share of the mod_state area, implemented by the game and reached through Host.

Provided Methods

fn attachment_query(&self, namespace: &str, name: &str) -> AttachmentBatch

Side: both. Capture a SNAPSHOT of the current dimension’s attachment residency and values. Later changes require a fresh query. Removed-but-unswept entities may appear; writes through stale holders fail. Values are neither cloned nor eagerly decoded.

fn attachments(&mut self) -> &mut dyn AttachmentStore

Side: both. The server-owned holders’ attachments; TYPE.get(host, holder) reads one. On a client it is the copy of what the server synced: set and remove change only the copy.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
