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

An AST node that stores its original position.

Fields§

§pos: Pos

The position of the node.

§node: T

The node itself.

Implementations§

source§

impl<T> Positioned<T>

source

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

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

source

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.

source

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

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

source

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

Map the inner value of this positioned node.
