Module shrinkable 

Shrinkable — a layout modifier that allows its child to compress under an over-constraint.

By default every widget is rigid: when a stack runs out of main-axis room, rigid children keep their wanted size and overflow the bounds. Shrinkable opts a child into the over-constraint distribution: the stack divides any deficit across all shrinkable children proportional to their shrink weight, never below the min_width / min_height floor set here.

Shrinkable is the shrink counterpart to Expand: while Expand claims leftover slack (grow), Shrinkable absorbs excess pressure (shrink). The two are independent — a child can both grow on surplus and shrink on deficit by wrapping with Shrinkable and setting a non-zero flex on the inner widget.

When to use

• A long text label that should ellipsize before a rigid icon/badge loses space.
• A thumbnail image column that may compress while a fixed sidebar stays at full width.
• “Compress A before B”: give A Shrinkable, leave B rigid (shrink = 0).

// The label shrinks as far as 48 dp; the button stays rigid.
let _row = HStack::new()
    .child(Shrinkable::new().min_width(48.0)
        .child(TextWidget::new(lit!("A long label that may compress")).single_line()))
    .child(TextWidget::new(lit!("Rigid")));

Shrinkable

Layout modifier that lets its child be compressed when a stack is over-constrained — the shrink counterpart to Expand.
