Struct QueryPatternVariablesFromDb

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

Query a function for variables of patterns defined within it.

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