EqualityState

cairo_lang_lowering::analysis::equality_analysis

Struct EqualityState 

Source 
pub struct EqualityState<'db> { /* private fields */ }
Expand description

State for the equality analysis, tracking variable equivalences.

This is the Info type for the dataflow analysis. Each block gets its own EqualityState representing what we know at that point in the program.

Uses sparse HashMaps for efficiency - only variables that have been touched by the analysis are stored.
