A config provider.
Required Methods§
Provided Methods§
Sourcefn may_resolve(&self, key: &Key<'_>) -> bool
fn may_resolve(&self, key: &Key<'_>) -> bool
Returns true if the given key might be resolvable by this Provider.
Dynamic resolvers will typically return true unconditionally, which is the default implementation.
