facet-dom

Tree-based (DOM) serialization and deserialization for facet.

Overview

This crate provides the core serializers and deserializers for tree-structured documents like HTML and XML. It handles the DOM-specific concerns that don't apply to flat formats like JSON:

• Tag names: Elements have names (<div>, <person>)
• Attributes: Key-value pairs on elements (id="main", class="active")
• Mixed content: Text and child elements can be interleaved

Architecture

facet-dom sits between the format-specific parsers (facet-html, facet-xml) and the generic facet reflection system:

facet-html / facet-xml
         ↓
     facet-dom  (DOM events: StartElement, Attribute, Text, EndElement)
         ↓
   facet-reflect (Peek/Poke)
         ↓
    Your Rust types

Key Types

DomDeserializer

Consumes DOM events and builds Rust values:

use facet_dom::{DomDeserializer, DomParser};

// Parser emits events, deserializer consumes them
let parser: impl DomParser = /* ... */;
let value: MyType = DomDeserializer::new(parser).deserialize()?;

DomSerializer

Converts Rust values to DOM events for output.

Field Mappings

The deserializer maps DOM concepts to Rust types using facet attributes:

Naming Conventions

Handles automatic case conversion between DOM naming (kebab-case) and Rust naming (snake_case), plus singularization for collection fields.
