Struct async_graphql_parser::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>

#[must_use]

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.

#[must_use]

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

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

#[must_use]

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

Map the inner value of this positioned node.

Trait Implementations
