[−][src]Function backtrace::resolve
pub fn resolve<F: FnMut(&Symbol)>(addr: *mut c_void, cb: F)
Resolve an address to a symbol, passing the symbol to the specified closure.
This function will look up the given address in areas such as the local symbol table, dynamic symbol table, or DWARF debug info (depending on the activated implementation) to find symbols to yield.
The closure may not be called if resolution could not be performed, and it also may be called more than once in the case of inlined functions.
Symbols yielded represent the execution at the specified addr
, returning
file/line pairs for that address (if available).
Required features
This function requires the std
feature of the backtrace
crate to be
enabled, and the std
feature is enabled by default.
Example
extern crate backtrace; fn main() { backtrace::trace(|frame| { let ip = frame.ip(); backtrace::resolve(ip, |symbol| { // ... }); false // only look at the top frame }); }
