Struct nih_plug_vizia::widgets::param_base::ParamWidgetData

pub struct ParamWidgetData<L, Params, P, FMap>where
    L: Lens<Target = Params> + Clone,
    Params: 'static,
    P: Param + 'static,
    FMap: Fn(&Params) -> &P + Copy + 'static,{ /* private fields */ }

Data and lenses that can be used to draw the parameter widget. The param field should only be used for looking up static data. Prefer the make_lens() function for binding parameter data to element properties.

Implementations

impl<L, Params, P, FMap> ParamWidgetData<L, Params, P, FMap>where L: Lens<Target = Params> + Clone, Params: 'static, P: Param + 'static, FMap: Fn(&Params) -> &P + Copy + 'static,

pub fn param(&self) -> &P

The parameter in question. This can be used for querying static information about the parameter. Don’t use this to get the parameter’s current value, use the lenses instead.

pub fn make_lens<R, F>(&self, f: F) -> impl Lens<Target = R>where F: Fn(&P) -> R + Clone + 'static, R: Clone + 'static,

Create a lens from a parameter’s field. This can be used to bind one of the parameter’s value getters to a property.

Trait Implementations

impl<L, Params, P, FMap> Clone for ParamWidgetData<L, Params, P, FMap>where L: Lens<Target = Params> + Clone, Params: 'static, P: Param + 'static, FMap: Fn(&Params) -> &P + Copy + 'static,

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
