Implementations

impl RestrictionKind

pub fn is_allowed_in(self, module: DefId, tcx: TyCtxt<'_>) -> bool

Returns true if the behavior is allowed/unrestricted in the given module. A value of false indicates that the behavior is prohibited.

pub fn expect_span(self) -> Span

Obtain the Span of the restriction. Panics if the restriction is unrestricted.

pub fn restriction_path(self, tcx: TyCtxt<'_>) -> String

Obtain the path of the restriction. If unrestricted, an empty string is returned.

pub fn stricter_of(self, rhs: Self, tcx: TyCtxt<'_>) -> Self

Obtain the stricter restriction between self and rhs. Panics if the restrictions do not reference the same crate.
