Struct rustc_data_structures::graph::iterate::CycleDetector

source · 
pub struct CycleDetector;
Expand description

This TriColorVisitor looks for back edges in a graph, which indicate that a cycle exists.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
