Re-exports§

sample: Float and Sample - the precision-routing traits that let plugin code stay in one float type without per-call-site casts.

BoolParam: A boolean parameter.
EnumParam: An enum parameter.
FloatParam: A continuous floating-point parameter.
IntParam: An integer parameter.
MeterSlot: A meter slot with an auto-assigned ID.
ParamFlags
ParamInfo: Metadata for a single parameter, used by format wrappers.
Smoother: Per-parameter smoother. All methods take &self for interior mutability, enabling use through Arc<Params>.

MidiSource: The MIDI message a parameter binds to for host MIDI-learn. CCs cover the common case; the non-CC per-channel messages each map onto a VST3 ControllerNumbers value, an AU status byte, and an LV2 midi:binding class.
ParamRange: Defines how a parameter maps between plain and normalized values.
ParamUnit
ParamValueKind: Which strongly-typed *Param constructor produced this ParamInfo. The #[derive(Params)] macro sets it from the field type so format-side code can branch on the original typing without re-deriving it from range / unit.
SmoothingStyle: Smoothing style for a parameter.

FloatParamReadF32: Precision-routed read accessors for FloatParam at f32.
FloatParamReadF64: Precision-routed read accessors for FloatParam at f64. See FloatParamReadF32 for the contract.
ParamEnum: Trait for enums used as parameters.
Params: Trait implemented by #[derive(Params)] on a struct. Format wrappers use this to enumerate, read, and write parameters.

format_param_value: Format a plain parameter value as a display string based on the parameter’s unit.
map_source_to_param: Resolve which parameter a MIDI source on channel is bound to, from a param-info list. The first param whose binding matches the source and whose channel scope is unset (any) or equal wins; #[derive(Params)] rejects ambiguous overlaps at compile time, so at most one matches. Used by the format wrappers’ mapping paths.
