Struct ResolverMacroData 

pub struct ResolverMacroData {
    pub defsite_module_file_id: ModuleFileId,
    pub callsite_module_file_id: ModuleFileId,
    pub expansion_mappings: Arc<[CodeMapping]>,
    pub parent_macro_call_data: Option<Box<ResolverMacroData>>,
}

Resolving data needed for resolving macro expanded code in the correct context.

Fields

defsite_module_file_id: ModuleFileId

The module file id of the macro definition site. It is used if the path begins with $defsite.

callsite_module_file_id: ModuleFileId

The module file id of the macro call site. Items are resolved in this context in two cases:

1. The path begins with $callsite.
2. The path was supplied as a macro argument. In other words, the path is an expansion of a placeholder and is not a part of the macro expansion template.

expansion_mappings: Arc<[CodeMapping]>

This is the mappings of the macro expansion. It is used to determine if a part of the code came from a macro argument or from the macro expansion template.

parent_macro_call_data: Option<Box<ResolverMacroData>>

The parent macro data. Exists in case of a macro calling another macro, and is used if we climb to the callsite environment.
