Struct PackedBoxProps 

#[repr(C)]
pub struct PackedBoxProps {
    pub margin: [i16; 4],
    pub padding: [i16; 4],
    pub border: [i16; 4],
    pub margin_auto: MarginAuto,
}

Packed representation of box model properties using i16×10 encoding.

Stores margin/padding/border as i16 values scaled by 10 (0.1px precision), reducing the hot struct from 52B to 26B. Range: ±3276.7px per edge.

Only used for storage in LayoutNodeHot. The layout solver unpacks to ResolvedBoxProps (f32) for computation.

Fields

margin: [i16; 4]

padding: [i16; 4]

border: [i16; 4]

margin_auto: MarginAuto

Implementations

impl PackedBoxProps
