Struct Location 

pub struct Location {
    pub line: u64,
    pub column: u64,
}

Location in input string

Create an “empty” (unknown) Location

let location = Location::empty();

Create a Location from a line and column

let location = Location::new(1, 1);

Create a Location from a pair

let location = Location::from((1, 1));

Fields

line: u64

Line number, starting from 1.

Note: Line 0 is used for empty spans

column: u64

Line column, starting from 1.

Note: Column 0 is used for empty spans

Implementations

impl Location

pub fn empty() -> Location

Return an “empty” / unknown location

pub fn new(line: u64, column: u64) -> Location

Create a new Location for a given line and column

pub fn of(line: u64, column: u64) -> Location

Create a new location for a given line and column

Alias for Self::new

pub fn span_to(self, end: Location) -> Span

Combine self and end into a new Span

Trait Implementations

impl AsNodeKey for Location

fn as_node_key(&self) -> NodeKey<'_>

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<(), Error>

Formats the value using the given formatter.

impl Display for Location

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

Formats the value using the given formatter.

impl From<(u64, u64)> for Location

fn from(_: (u64, u64)) -> Location

Converts to this type from the input type.

impl Hash for Location

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

where __H: Hasher,

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.

fn apply_transform_with_path<T>( &'ast self, transformer: &mut T, node_path: &mut NodePath<'ast>, ) -> Result<Self, T::Error>

where T: Transform<'ast>,

Recursively applies transform to self returning Ok(Self) when successful or Err(T::Error) if unsuccessful.

fn apply_transform<T>(&'ast self, transform: &mut T) -> Result<Self, T::Error>

where T: Transform<'ast>,

Recursively applies transform to self returning Ok(Self) when successful or Err(T::Error) if unsuccessful.

impl Visitable for Location

fn accept<'ast, V: Visitor<'ast>>( &'ast self, visitor: &mut V, ) -> ControlFlow<Break<V::Error>>

Accepts a borrowed Visitor and traverses the AST starting at self invoking Visitor::enter and Visitor::exit as nodes are entered and exiting respectively.

fn downcast_ref<Target: Visitable>(&self) -> Option<&Target>
