RetainedDepGraph

rustc_middle::dep_graph

Struct RetainedDepGraph 

Source 
pub struct RetainedDepGraph {
    pub inner: LinkedGraph<DepNode, ()>,
    pub indices: FxHashMap<DepNode, NodeIndex>,
    pub dep_index_to_index: IndexVec<DepNodeIndex, Option<NodeIndex>>,
}
Expand description

An in-memory copy of the current session’s query dependency graph, which is only enabled when -Zquery-dep-graph is set (for debugging/testing).

Normally, dependencies recorded during the current session are written to disk and then forgotten, to avoid wasting memory on information that is not needed when the compiler is working correctly.

Fields§

§inner: LinkedGraph<DepNode, ()>§indices: FxHashMap<DepNode, NodeIndex>§dep_index_to_index: IndexVec<DepNodeIndex, Option<NodeIndex>>
