Function find_class_by_name

src/util.rs:791–805

Find a class in a slice by name, preferring namespace-aware matching when the name is fully qualified. When `name` contains backslashes (e.g. `Illuminate\Database\Eloquent\Builder`), the lookup checks each candidate's `file_namespace` field so that the correct class is returned even when multiple classes share the same short name but live in different namespace blocks within the same file (e.g. `

(
    all_classes: &'a [Arc<ClassInfo>],
    name: &str,
)

/// When `name` is a bare short name (no backslashes), the first class with
/// a matching `name` field is returned (preserving existing behavior).
pub(crate) fn find_class_by_name<'a>(
    all_classes: &'a [Arc<ClassInfo>],
    name: &str,
) -> Option<&'a Arc<ClassInfo>> {
    let short = short_name(name);

    if name.contains('\\') {
        let expected_ns = name.rsplit_once('\\').map(|(ns, _)| ns);
        all_classes
            .iter()
            .find(|c| c.name == short && c.file_namespace.as_deref() == expected_ns)
