impl<'a> Symbol<'a>

fn name(&self) -> Option<&str>

fn is_external(&self) -> bool

Trait Implementations

impl<'a> Debug for Symbol<'a>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a> Display for Symbol<'a>

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

Formats the value using the given formatter.

impl<'a> SymbolReference for Symbol<'a>

fn desc(&self) -> u16

raw desc value

fn ref_type(&self) -> u8

types of references

fn is_ref_dyn(&self) -> bool

To simplify stripping of objects that use are used with the dynamic link editor, the static link editor marks the symbols defined an object that are referenced by a dynamicly bound object (dynamic shared libraries, bundles). With this marking strip knows not to strip these symbols.

fn lib_ordinal(&self) -> u8

The ordinal recorded references the libraries listed in the Mach-O file

fn is_no_dead_strip(&self) -> bool

symbol is not to be dead stripped

fn is_discarded(&self) -> bool

symbol is discarded

fn is_weak_ref(&self) -> bool

symbol is weak referenced

fn is_weak_def(&self) -> bool

coalesed symbol is a weak definition

fn is_ref_to_weak(&self) -> bool

reference to a weak symbol

fn is_arm_thumb_def(&self) -> bool

symbol is a Thumb function (ARM)

fn is_resolver(&self) -> bool

the function is actually a resolver function and should be called to get the address of the real function to use.

fn is_alt_entry(&self) -> bool

symbol is pinned to the previous content.
