Enum VisibleWhen 

pub enum VisibleWhen {
    Always,
    AdvancedOn,
    AdvancedOff,
    Never,
}

Conditional visibility for a field — the data-driven analogue of MatterCAD’s IPropertyGridModifier.UpdateControls(change) hook.

The host knows which sibling boolean property gates the AdvancedOn / AdvancedOff rows (typically a bool named advanced); the UI layer filters rows before rendering based on the live value of that toggle.

Variants

Always

Always render (default).

AdvancedOn

Render only when the node’s advanced toggle is on. MatterCAD’s IPropertyGridModifier.UpdateControls pattern for advanced rows.

AdvancedOff

Render only when the node’s advanced toggle is off. Used by the easy-mode hint message that nudges the user toward Advanced.

Never

Never render. MatterCAD’s [HideFromEditor].

Trait Implementations

impl Clone for VisibleWhen

fn clone(&self) -> VisibleWhen

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VisibleWhen

impl Debug for VisibleWhen

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

Formats the value using the given formatter.

impl Default for VisibleWhen

fn default() -> VisibleWhen

Returns the “default value” for a type.

impl Eq for VisibleWhen

impl PartialEq for VisibleWhen

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