Concept List

Here is a list of all concepts with brief descriptions:

Nultralight	Root namespace for every public Ultralight type, function, and enumeration
Ndom	Direct C++ access to modify page elements and handle events
Ndata	Data-binding API that connects native C++ data to HTML and CSS markup
RBindable	Whether or not T binds as a leaf value (ignoring const, volatile, and references), ie
RBindableHolder	Whether or not Context::Bind() can bind an instance through H
RDescribed	Whether or not T has a schema (ignoring const, volatile, and references), ie
RScalarPayload	Whether or not P can be an action's payload without a payload struct (ignoring const, volatile, and references)
RLockableHolder	Whether or not the DOM API can hold an object through H (ignoring const and references), ie
Njs	Type-checked JavaScript bridge between C++ and web pages
RHolder	Whether or not H (ignoring const and references) is an owning holder: its ultralight::HolderTraits declares element_type, kind, and Get()
RLockableHolder	Whether or not H (ignoring const and references) is a weak holder: its ultralight::HolderTraits declares element_type and a Lock() that returns an owning holder
RMarshalable	Whether or not js::TypeTraits can convert T (ignoring const, volatile, and references)
RBitmaskEnum	Whether or not a scoped enum has opted into the bitmask operators below by declaring consteval void ul_enable_bitmask_operators(E); beside its definition (found by argument-dependent lookup)
RLayoutBuildable	A builder element (see <AppCore/layout/Builder.h>): anything that can append itself to a container
