Source§impl DynamicLibrary
impl DynamicLibrary
Sourcepub fn open(filename: Option<&Path>) -> Result<Self, String>
pub fn open(filename: Option<&Path>) -> Result<Self, String>
Lazily loads the dynamic library named filename into memory and
then returns an opaque “handle” for that dynamic library.
Returns a handle to the calling process when passed None.
Sourcepub fn prepend_search_path(path: &Path)
pub fn prepend_search_path(path: &Path)
Prepends a path to this process’s search path for dynamic libraries
Sourcepub fn create_path(path: &[PathBuf]) -> OsString
pub fn create_path(path: &[PathBuf]) -> OsString
From a slice of paths, create a new vector which is suitable to be an environment variable for this platforms dylib search path.
Sourcepub fn envvar() -> &'static str
pub fn envvar() -> &'static str
Returns the environment variable for this process’s dynamic library search path
Sourcepub fn search_path() -> Vec<PathBuf>
pub fn search_path() -> Vec<PathBuf>
Returns the current search path for dynamic libraries being used by this process
Sourcepub unsafe fn symbol<T>(&self, symbol: &str) -> Result<*mut T, String>
pub unsafe fn symbol<T>(&self, symbol: &str) -> Result<*mut T, String>
Returns the address of where symbol symbol was loaded into memory.
In POSIX compliant systems, we return ‘Err’ if the symbol was not found, in this library or any of the libraries that were automatically loaded when this library was loaded.
Sourcepub unsafe fn symbol_special<T>(
handle: SpecialHandles,
symbol: &str,
) -> Result<*mut T, String>
pub unsafe fn symbol_special<T>( handle: SpecialHandles, symbol: &str, ) -> Result<*mut T, String>
Returns the address of the first occurance of symbol symbol using the
default library search order if you use SpecialHandles::Default.
Returns the address of the next occurance of symbol symbol after the
current library in the default library search order if you use
SpecialHandles::Next.
