webots-proto

Facade crate for working with Webots PROTO files.

Use this crate when you want one dependency that exposes:

• parsing via Proto
• template rendering via ProtoExt::render()
• validation via ProtoExt::validate()
• EXTERNPROTO expansion via ProtoResolver
• typed R2025a nodes via r2025a

Features

• template
• resolver
• schema
• validation
• r2025a

Default features enable the full façade.

Example

use webots_proto::{Proto, ProtoExt, RenderOptions};

let proto: Proto = r#"#VRML_SIM R2025a utf8
PROTO Demo [] { Group {} }
"#
.parse()?;

let rendered = proto.render(&RenderOptions::default())?;
let diagnostics = proto.validate()?;
assert!(!diagnostics.has_errors());
# Ok::<(), Box<dyn std::error::Error>>(())

Use the companion crates directly if you only want one layer of functionality.
