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.
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"); impl<'a> Location<'a>
[src]
pub fn file(&self) -> &str
[src]
Returns the name of the source file from which the panic originated.
use std::panic;
panic::set_hook(Box::new(|panic_info| {
if let Some(location) = panic_info.location() {
println!("panic occurred in file '{}'", location.file());
} else {
println!("panic occurred but can't get location information...");
}
}));
panic!("Normal panic"); pub fn line(&self) -> u32
[src]
Returns the line number from which the panic originated.
use std::panic;

panic!("Normal panic"); pub fn column(&self) -> u32
[src]
Returns the column from which the panic originated.
