详细描述

StyleValuePool allows compact storage for a sparse collection of assigned lengths and numbers. Values are referred to using StyleValueHandle. In most cases StyleValueHandle can embed the value directly, but if not, the value is stored within a buffer provided by the pool. The pool contains a fixed number of inline slots before falling back to heap allocating additional slots.
