Struct Positioned

pub struct Positioned<T: ?Sized> {
    pub pos: Pos,
    pub node: T,
}

An AST node that stores its original position.

Fields

pos: Pos

The position of the node.

node: T

The node itself.

Implementations

impl<T> Positioned<T>

pub const fn new(node: T, pos: Pos) -> Positioned<T>

Create a new positioned node from the node and its position.

pub fn into_inner(self) -> T

Get the inner node.

This is most useful in callback chains where Positioned::into_inner is easier to read than |positioned| positioned.node.

pub fn position_node<U>(&self, other: U) -> Positioned<U>

Create a new positioned node with the same position as this one.

pub fn map<U>(self, f: impl FnOnce(T) -> U) -> Positioned<U>

Map the inner value of this positioned node.

Trait Implementations

impl Borrow<str> for Positioned<String>

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl BorrowMut<str> for Positioned<String>

fn borrow_mut(&mut self) -> &mut str

Mutably borrows from an owned value.

impl<T: Clone + ?Sized> Clone for Positioned<T>

fn clone(&self) -> Positioned<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + ?Sized> Debug for Positioned<T>

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

Formats the value using the given formatter.

impl<T: Default + ?Sized> Default for Positioned<T>

fn default() -> Positioned<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Positioned<T>

where T: Deserialize<'de> + ?Sized,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Display> Display for Positioned<T>

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

Formats the value using the given formatter.

impl<T: Hash> Hash for Positioned<T>

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<T: Ord> Ord for Positioned<T>

fn cmp(&self, other: &Self) -> 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<T: PartialEq> PartialEq for Positioned<T>

fn eq(&self, other: &Self) -> 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<T: PartialOrd> PartialOrd for Positioned<T>

fn partial_cmp(&self, other: &Self) -> 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<T> Serialize for Positioned<T>

where T: Serialize + ?Sized,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
