pub fn host_function_path(spec: &TraitBridgeSpec<'_>, fn_name: &str) -> StringExpand description
Resolve the FQN of a host-crate plugin function (e.g.
kreuzberg::plugins::ocr::unregister_ocr_backend) given the bridge’s
registry_getter path. The convention used by host crates is:
registry_getter = "kreuzberg::plugins::registry::get_ocr_backend_registry"- top-level fn =
kreuzberg::plugins::ocr::unregister_ocr_backend
We rewrite ::registry::get_*_registry to ::<sub>::<fn_name> where
<sub> is the trait submodule name (extracted from _*_registry).
When the heuristic fails (no registry_getter, unexpected shape), we
fall back to {core_import}::plugins::{fn_name} so the user can rely on
a re-export.
Shared by every backend that opts in to unregister_*/clear_* codegen
(pyo3, napi, magnus, php, rustler, gleam, extendr, dart, swift, kotlin,
wasm). Replaces the duplicated <lang>_host_function_path helpers that
each backend used to define.
