ty::[−][src] print:: with_no_queries
pub fn with_no_queries<F: FnOnce() -> R, R>(f: F) -> R
Avoids running any queries during any prints that occur
during the closure. This may alter the appearance of some
types (e.g. forcing verbose printing for opaque types).
This method is used during some queries (e.g.
for opaque types), to ensure that any debug printing that
occurs during the query computation does not end up recursively
calling the same query.
