fn info_from_return( &mut self, statement_location: StatementLocation, vars: &'a [VarUsage], ) -> Self::Info

Provided Methods§

source

fn visit_block_start( &mut self, info: &mut Self::Info, block_id: BlockId, block: &FlatBlock, )

source

fn visit_stmt( &mut self, info: &mut Self::Info, statement_location: StatementLocation, stmt: &'a Statement, )
