sourcepub const fn new(conditions: &'static [Condition], value: T) -> Self
pub const fn new(conditions: &'static [Condition], value: T) -> Self
Construct a new guarded value.

cx: JSContext,
obj: HandleObject<'_>,
global: HandleObject<'_>,
) -> Option<T>
pub fn expose( &self, cx: JSContext, obj: HandleObject<'_>, global: HandleObject<'_>, ) -> Option<T>
Expose the value if the conditions are satisfied.
The passed handle is the object on which the value may be exposed.
