Declaring a bounded parameter currently requires building a ParameterRange struct by hand: node.declare_parameter("speed") .default(0.5) .range(ParameterRange { lower: Some(0.0), upper: Some(1.0), step: None }) .mandatory()?; Most parameters have no step, so this is a lot of ceremony for a simple bound. Changing the builder to accept impl Into<T::Range> and adding a few conversion impl between Rust range types and ParameterRange would allow native Rust range syntax: node.declare_parameter("speed").default(0.5).range(0.0..=1.0).mandatory()?; node.declare_parameter("count").default(5).range(0..10).mandatory()?; node.declare_parameter("offset").default(-3).range(..=0).mandatory()?; We would need to add From impls into ParameterRange<T> for: RangeInclusive<T>, RangeFrom<T>, RangeToInclusive<T>, RangeFull, generic over T: ParameterVariant + PartialOrd Range<i64> and RangeTo<i64>, converting the exclusive end into the inclusive bound end - 1 Range<f64> and RangeTo<f64> should
