Description: API documentation for the Rust `Location` struct in crate `std`.
Keywords: rust, rustlang, rust-lang, Location

# Struct std::panic::Location 1.10.0 [−] [src]

    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]

#### `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

#### `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

#### `fn column(&self) -> u32`
[src]

🔬 This is a nightly-only experimental API. (`panic_col` #42939)

recently added

Returns the column from which the panic originated.

# Examples

    #![feature(panic_col)]
    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

## Trait Implementations

### `impl<'a> Debug for Location<'a>`
[src]

#### `fn fmt(&self, __arg_0: &mut Formatter) -> Result`
[src]

Formats the value using the given formatter.

## 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`)
