}

Functions for the debug support part of libstd (e.g. unwinding, backtracing).

Required Methods

fn get_library(&self, id: LibraryId) -> Option<Library>

Gets a handle to a library given the ID.

fn get_exeid(&self) -> Option<LibraryId>

Returns the ID of the main executable, if there is one.

fn get_library_segment(&self, lib: &Library, seg: usize) -> Option<AddrRange>

Get a segment of a library, if the segment index exists. All segment IDs are indexes, so they range from [0, N).

fn get_full_mapping(&self, lib: &Library) -> Option<ObjectHandle>

Get the full mapping of the underlying library.

fn iterate_phdr(&self, f: &mut dyn FnMut(DlPhdrInfo) -> c_int) -> c_int

Handler for calls to the dl_iterate_phdr call.

Provided Methods

fn next_library_id(&self, id: LibraryId) -> Option<LibraryId>

Get the library ID immediately following the given one.
