Struct QueryPatternVariablesFromDb 

Source 
pub struct QueryPatternVariablesFromDb<'a>(pub &'a (dyn Database + 'static), pub FunctionWithBodyId<'a>);
Expand description

Query a function for variables of patterns defined within it.

This is a wrapper over Database that takes FunctionWithBodyId and relays queries to FunctionWithBodySemantic::pattern_semantic.
