Struct BackendAttrs 

pub struct BackendAttrs<'a> {
    pub current_node_attributes: &'a [AttributeProto],
    pub current_node_metadata: &'a [StringStringEntryProto],
}

Per-call NodeProto context surfaced to Backend::execute so kernels overriding the whole-graph path see the original call site’s attributes + metadata alongside the body. Per-op methods (which receive their attributes positionally as typed args) don’t need this struct.

Fields

current_node_attributes: &'a [AttributeProto]

Attribute list from the call NodeProto’s attribute field.

current_node_metadata: &'a [StringStringEntryProto]

metadata_props from the call NodeProto.
