Trait AttachmentQueries 

pub trait AttachmentQueries: Host {
    // Provided method
    fn query<'key, T>(
        &self,
        key: &'key AttachmentType<T>,
    ) -> Result<AttachmentQuery<'key, AttachmentHolder, T>, AttachmentError>
       where T: Send + Sync + 'static { ... }
}

Read queries available on either host side.

Provided Methods

fn query<'key, T>( &self, key: &'key AttachmentType<T>, ) -> Result<AttachmentQuery<'key, AttachmentHolder, T>, AttachmentError>

where T: Send + Sync + 'static,

Capture a SNAPSHOT of membership and value bindings in the current dimension. Later changes appear only in fresh queries. This is a residency view: an entity removed but not yet swept may still appear; stale writes fail. Construction never clones or decodes values; iteration decodes lazily.

Dyn Compatibility

This trait is not dyn compatible.

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