# 1.10.0[−][src]Struct core::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) -> u32`
1.25.0
[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

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
