Struct RelocatedDylib

pub struct RelocatedDylib {
    pub inner: Arc<Dylib>,
}

A dynamic library that has been relocated

Fields

inner: Arc<Dylib>

Implementations

impl RelocatedDylib

pub fn dep_libs(&self) -> Option<&[RelocatedDylib]>

Get dependent libraries.

Examples

if let Some(dependencies) = library.dep_libs() {
    for lib in dependencies {
        println!("Dependency: {:?}", lib);
    }
} else {
    println!("No dependencies found.");
}

pub fn name(&self) -> &str

Get the name of the dynamic library.

pub fn cname(&self) -> &CStr

Get the C-style name of the dynamic library.

pub fn base(&self) -> usize

Get the base address of the dynamic library.

pub fn user_data(&self) -> &UserData

Get the user data of the dynamic library.

pub unsafe fn get<'lib, T>( &'lib self, name: &str, ) -> Result<Symbol<'lib, T>, Error>

Get a pointer to a function or static variable by symbol name.

The symbol is interpreted as-is; no mangling is done. This means that symbols like x::y are most likely invalid.

Safety

Users of this API must specify the correct type of the function or variable loaded.

Examples

unsafe {
    let awesome_function: Symbol<unsafe extern fn(f64) -> f64> =
        lib.get("awesome_function").unwrap();
    awesome_function(0.42);
}

A static variable may also be loaded and inspected:

unsafe {
    let awesome_variable: Symbol<*mut f64> = lib.get("awesome_variable").unwrap();
    **awesome_variable = 42.0;
};
