Struct Location 

pub struct Location { /* private fields */ }

A serializable source code location.

This is meant to be a drop in replacement for std::panic::Location with the added benefit that it implements Serialize and Deserialize.

In practice, this is useful when you want to capture caller information and store it, send it across process boundaries, or include it in serialized data.

For behavior and semantics, see std::panic::Location.

Implementations

impl Location

pub const fn caller() -> Self

Returns the caller location.

See std::panic::Location::caller for details.

pub const fn file(&self) -> &str

Returns the file name.

See std::panic::Location::file for details.

pub const fn column(&self) -> u32

Returns the column number.

See std::panic::Location::column for details.

pub const fn line(&self) -> u32

Returns the line number.

See std::panic::Location::line for details.

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<'de> Deserialize<'de> for Location

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Location

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

Formats this location as file:line:column.

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

Converts a static std::panic::Location into a Location.

std::panic::Location::caller() returns a 'static location, so this conversion can borrow the file path without allocating.

fn from(location: &'static 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.

impl Serialize for Location

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Location
