Struct DynLib 

pub struct DynLib { /* private fields */ }

Implementations

impl DynLib

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

Load a dynamic library from the given path.

Safety

The target file must be a valid dynamic library for the current process.

pub fn from_library(library: Library, path: impl Into<PathBuf>) -> Self

Wrap an already-loaded libloading::Library.

Useful when the library was loaded elsewhere (e.g. by the OS or another loader) and only reference-counting ownership is needed here.

pub fn unowned() -> Self

A handle that does NOT own the library (no unload on drop).

For refs obtained from plugins whose library lifetime is managed externally (e.g. statically linked, or kept alive by another handle). Uses dlopen(NULL) — a handle to the current process, which never fails and whose “unload” is a no-op.

pub fn path(&self) -> &Path

pub unsafe fn symbol<T: Copy>(&self, name: &[u8]) -> Result<T>

Load a symbol from the library.

Safety

The caller must ensure T matches the actual exported symbol type.

pub unsafe fn try_symbol<T: Copy>(&self, name: &[u8]) -> Option<T>

Try to load a symbol; returns None if not found.

Safety

The caller must ensure T matches the actual exported symbol type.

Trait Implementations

impl Clone for DynLib

fn clone(&self) -> DynLib

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
