Struct LoadedDll 

pub struct LoadedDll {
    pub path: PathBuf,
    pub name: String,
    lib: Library,
    symbols: HashMap<String, *const ()>,
    pub registered_calls: HashMap<String, *const ()>,
    pub registered_c_methods: HashMap<String, *const ()>,
}

A loaded dynamic library and its resolved symbols.

Fields

path: PathBuf

Path to the .so/.dylib file.

name: String

Short name (e.g. “myPkg” from “myPkg.so”).

lib: Library

The underlying library handle.

symbols: HashMap<String, *const ()>

Cached symbol addresses: function name → raw pointer.

registered_calls: HashMap<String, *const ()>

.Call methods registered via R_registerRoutines during R_init_.

registered_c_methods: HashMap<String, *const ()>

.C methods registered via R_registerRoutines during R_init_.

Implementations

impl LoadedDll

pub fn load(path: &Path) -> Result<Self, String>

Load a shared library from the given path, then call R_init_ if it exists (to register routines).

fn call_pkg_init(&mut self, pkg_name: &str)

Call the package init function R_init_<name>(DllInfo*) if present.

fn collect_registered_calls(&mut self)

Read registered .Call and .C methods from the Rust runtime’s registry.

pub fn get_c_symbol(&mut self, name: &str) -> Result<*const (), String>

Look up a .C method symbol by name. Checks registered .C methods first, then falls back to dynamic symbol lookup.

pub fn get_symbol(&mut self, name: &str) -> Result<*const (), String>

Look up a function symbol by name. Checks registered .Call routines first, then falls back to dynamic symbol lookup. Caches the result.
