Struct ConditionContext 

pub struct ConditionContext {
    pub width: f32,
    pub height: Option<f32>,
    pub hover: bool,
    pub reduced_motion: bool,
    pub states: Vec<String>,
    pub breakpoints: IndexMap<String, f32>,
    pub form_factor: Option<FormFactor>,
}

What a client knows when it flattens a style: the SURFACE box, the platform’s pointer and motion preference, the node’s interaction states and the theme’s breakpoint values (px).

Fields

width: f32

height: Option<f32>

hover: bool

A hover-capable pointer (mouse, trackpad); false on touch.

reduced_motion: bool

The platform asks for reduced motion.

states: Vec<String>

The node’s active states, the state keys without the colon (hover, focus-visible, pressed).

breakpoints: IndexMap<String, f32>

$breakpoint.<name> → px.

form_factor: Option<FormFactor>

VAPP-218: the host’s form factor; None = derived from the width (form_factor_of).
