Struct ra_ap_cfg::DnfExpr [−][src]
A #[cfg] directive in Disjunctive Normal Form (DNF).
Implementations
impl DnfExpr[src]
pub fn new(expr: CfgExpr) -> Self[src]
pub fn why_inactive(&self, opts: &CfgOptions) -> Option<InactiveReason>[src]
Computes a list of present or absent atoms in opts that cause this expression to evaluate
to false.
Note that flipping a subset of these atoms might be sufficient to make the whole expression
evaluate to true. For that, see compute_enable_hints.
Returns None when self is already true, or contains errors.
pub fn compute_enable_hints<'a>(
&'a self,
opts: &'a CfgOptions
) -> impl Iterator<Item = CfgDiff> + 'a[src]
&'a self,
opts: &'a CfgOptions
) -> impl Iterator<Item = CfgDiff> + 'a
Returns CfgDiff objects that would enable this directive if applied to opts.
