Struct Calc 

pub struct Calc(/* private fields */);

An expression that depends on the room, by its place in the table. Copy, so a Sizing holding one still is.

Implementations

impl Calc

pub fn resolve(self, room: f32) -> f32

The expression in logical px of room px — evaluated under the table’s read lock, since layout asks once per node that has one.

pub fn expr(self) -> Option<Arc<Expr>>

The tree the handle names.

pub fn id(self) -> u32

The handle’s number: what a binding carries across (the C ABI’s KUI_CALC sizing holds it in its value).

pub fn from_id(id: u32) -> Option<Calc>

A handle by number, when the table has one there.

pub fn describe(self) -> String

The canonical spelling (clamp(400px, 80%, 1000px)), for a reader.
