Struct graphql_toolkit_parser::Positioned

pub struct Positioned<T>
where
    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

where T: Default + ?Sized,

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<Positioned<T>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> Display for Positioned<T>

where T: Display,

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

Formats the value using the given formatter.

impl<T> Hash for Positioned<T>

where T: Hash,

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<T> Ord for Positioned<T>

where T: Ord,

fn cmp(&self, other: &Positioned<T>) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl<T> PartialEq for Positioned<T>

where T: PartialEq,

fn eq(&self, other: &Positioned<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T> PartialOrd for Positioned<T>

where T: PartialOrd,

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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