Struct Location 

pub struct Location { /* private fields */ }

Represents a source code location (file, line, column).

Location is used to track where errors are created and propagated, providing detailed backtraces for debugging.

Creation

Locations are typically created automatically by methods with #[track_caller]:

use error2::Location;

let loc = Location::caller(); // Captures current location
println!("At {}:{}:{}", loc.file(), loc.line(), loc.column());

Usage in Backtraces

Locations are automatically recorded when using .context(), .attach(), .build(), and other error handling methods.

Implementations

impl Location

pub fn caller() -> Self

Captures the caller’s location using #[track_caller].

pub fn file(&self) -> &'static str

Returns the file path.

pub const fn line(&self) -> u32

Returns the line number.

pub const fn column(&self) -> u32

Returns the column number.

pub fn from_std(location: &Location<'static>) -> Self

Converts from std::panic::Location.

Trait Implementations

impl Clone for Location

fn clone(&self) -> Location

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Location

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Location

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<&'a Location<'static>> for Location

fn from(location: &'a Location<'static>) -> Self

Converts to this type from the input type.

impl Hash for Location

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Location

fn cmp(&self, other: &Location) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Location

fn eq(&self, other: &Location) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Location

fn partial_cmp(&self, other: &Location) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
