A complete definition of one parameter a node accepts. Provides everything the engine (validation) and UI (control rendering) need.

Fields

name: String

label: String

description: String

param_type: ParameterType

Value type — determines what UI control to render.

default: Option<Value>

constraints: Option<Constraints>

placeholder: Option<String>

visible_when: Option<ParamCondition>

required_when: Option<ParamCondition>

surfaceable: bool

Whether this param can be surfaced in container config panels.

group: Option<String>

suffix: Option<String>

control: Option<String>

Override control identifier (e.g., "slider", "select", "file").

accept: Option<Vec<String>>

presets: Option<Vec<PresetEntry>>

inverted: Option<bool>

Flip the semantic of a boolean control.

Trait Implementations

impl Clone for ParameterDef

fn clone(&self) -> ParameterDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterDef

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

Formats the value using the given formatter.

impl Default for ParameterDef

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ParameterDef

fn eq(&self, other: &ParameterDef) -> 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.

impl Serialize for ParameterDef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
