Struct Vst3ParamInfo 

pub struct Vst3ParamInfo {
    pub id: u32,
    pub stable_id: String,
    pub title: String,
    pub units: String,
    pub min: f64,
    pub max: f64,
    pub default: f64,
    pub automatable: bool,
}

A VST3 parameter declaration.

Captures the host-facing identity and value range of one automatable parameter; to_parameter_descriptor lowers it into the shared plugin-core ParameterDescriptor.

Fields

id: u32

The numeric VST3 parameter id.

stable_id: String

The stable string id used for persistence and lookup.

title: String

The human-readable parameter title.

units: String

The display units, empty when the parameter is unitless.

min: f64

The minimum parameter value.

max: f64

The maximum parameter value.

default: f64

The default value, clamped into the min..=max range.

automatable: bool

Whether the host may automate the parameter.

Implementations

impl Vst3ParamInfo

pub fn new( id: u32, stable_id: impl Into<String>, title: impl Into<String>, min: f64, max: f64, default: f64, ) -> Result<Self>

Builds a parameter, validating ids and range.

Requires non-empty stable_id and title and min <= max; default is clamped into the range, units starts empty, and automatable defaults to true. Returns an error when validation fails.

pub fn to_parameter_descriptor(&self) -> Result<ParameterDescriptor>

Lowers this parameter into a plugin-core ParameterDescriptor with a Float kind.

Trait Implementations

impl Clone for Vst3ParamInfo

fn clone(&self) -> Vst3ParamInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Vst3ParamInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Vst3ParamInfo

fn eq(&self, other: &Vst3ParamInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
