1.10.0[−][src]Struct std::panic::Location
A struct containing information about the location of a panic.
This structure is created by the location
method of PanicInfo
.
Examples
use std::panic; panic::set_hook(Box::new(|panic_info| { if let Some(location) = panic_info.location() { println!("panic occurred in file '{}' at line {}", location.file(), location.line()); } else { println!("panic occurred but can't get location information..."); } })); panic!("Normal panic");Run
