Struct AddressInfo 

#[non_exhaustive]
pub struct AddressInfo {
    pub library: PathBuf,
    pub library_base: *mut c_void,
    pub symbol: Option<CString>,
    pub symbol_address: *mut c_void,
}

What the loader knows about an address: the library containing it and, where available, the nearest exported symbol.

let strlen = unsafe { lib.get::<*const u8>(c"strlen") }.unwrap();
let info = AddressInfo::of(strlen.as_ptr()).unwrap();
println!("strlen lives in {}", info.library.display());

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

library: PathBuf

Path of the library (or executable) containing the address.

library_base: *mut c_void

Address the library is loaded at.

symbol: Option<CString>

Name of the nearest exported symbol at or below the address (Unix only; None on Windows or if there is none).

symbol_address: *mut c_void

Address of that symbol (null if there is none).

Implementations

impl AddressInfo

pub fn of(addr: *const c_void) -> Option<AddressInfo>

Looks up addr (dladdr on Unix, GetModuleHandleExW + GetModuleFileNameW on Windows). Returns None if the address is not inside any loaded library.

Trait Implementations

impl Clone for AddressInfo

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AddressInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
