Struct Expander 

pub(super) struct Expander<'db> {
    span_map: SpanMap<'db>,
    current_file_id: HirFileId,
    ast_id_map: &'db AstIdMap,
    macro_depth: u32,
    recursion_limit: u32,
}

Fields

span_map: SpanMap<'db>

current_file_id: HirFileId

ast_id_map: &'db AstIdMap

macro_depth: u32

recursion_depth == u32::MAX indicates that the recursion limit has been reached.

recursion_limit: u32
