Struct std::panic::Location

pub struct Location<'a> { /* fields omitted */ }

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 occured in file '{}' at line {}", location.file(), location.line());
    } else {
        println!("panic occured but can't get location information...");
    }
}));

panic!("Normal panic");

Methods

impl<'a> Location<'a> [src]

Returns the name of the source file from which the panic originated.

Examples

use std::panic;

panic::set_hook(Box::new(|panic_info| {
    if let Some(location) = panic_info.location() {
        println!("panic occured in file '{}'", location.file());
    } else {
        println!("panic occured but can't get location information...");
    }
}));

panic!("Normal panic");

Returns the line number from which the panic originated.

Examples

use std::panic;

panic::set_hook(Box::new(|panic_info| {
    if let Some(location) = panic_info.location() {
        println!("panic occured at line {}", location.line());
    } else {
        println!("panic occured but can't get location information...");
