1.10.0[][src]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 occurred in file '{}' at line {}", location.file(), location.line());
    } else {
        println!("panic occurred but can't get location information...");
    }
}));

panic!("Normal panic");Run

Methods

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

pub fn file(&self) -> &str[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 occurred in file '{}'", location.file());
    } else {
        println!("panic occurred but can't get location information...");
    }
}));

panic!("Normal panic");Run

pub fn line(&self) -> u32[src]

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

panic!("Normal panic");Run

pub fn column(&self) -> u321.25.0[src]

Returns the column 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 occurred at column {}", location.column());
    } else {
        println!("panic occurred but can't get location information...");
    }
}));

panic!("Normal panic");Run
