Struct std::panic::PanicInfo1.10.0 [] [src]

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

A struct providing information about a panic.

PanicInfo structure is passed to a panic hook set by the set_hook() function.

Examples

use std::panic;

panic::set_hook(Box::new(|panic_info| {
    println!("panic occured: {:?}", panic_info.payload().downcast_ref::<&str>().unwrap());
}));

panic!("Normal panic");Run

Methods

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

Returns the payload associated with the panic.

This will commonly, but not always, be a &'static str or String.

Examples

use std::panic;

panic::set_hook(Box::new(|panic_info| {
    println!("panic occured: {:?}", panic_info.payload().downcast_ref::<&str>().unwrap());
}));

panic!("Normal panic");Run

Returns information about the location from which the panic originated, if available.

This method will currently always return Some, but this may change in future versions.

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");Run
