TreeBuilder

import { TreeBuilder } from "destack:tree";

Contextual builder for tree literals.

A node type opts into tree literals by implementing TreeBuilder.
The compiler resolves the builder from the literal's expected type, or
from the profile's configured default, checks lowercase tags against
Tags, and builds elements and fragments through the statics below.

export newtype interface TreeBuilder {
    Tags = {};
    static element<const Tag: keyof this.Tags, Children: (...unknown[],)>(tag: Tag, attributes: this.Tags[Tag], children: Children): this;
    static fragment<Children: (...unknown[],)>(children: Children): this;
}
