Crate dae_parser[−][src]
Expand description
A parser for the COLLADA format (.dae extension).
The main entry point is the Document type, which has a FromStr implementation to convert
literal strings / slices, or Document::from_file to read from a .dae file on disk.
Collada documents are parsed eagerly, validating everything according to the COLLADA schema. Once parsed, the data structures (structs and enums) can be navigated directly, as all the data structures are public, and reflect the XML schema closely.
This library implements only version 1.4.1 of the Collada spec, although it may be expanded in the future (PRs welcome).
