Struct Path 

pub struct Path { /* private fields */ }

A path through a type structure, recorded as a series of steps.

This is a lightweight representation that only stores indices. The actual field names and type information can be reconstructed by replaying these steps against the original Shape.

Implementations

impl Path

pub fn new() -> Self

Create a new empty path.

pub fn with_capacity(capacity: usize) -> Self

Create a path with pre-allocated capacity.

pub fn push(&mut self, step: PathStep)

Push a step onto the path.

pub fn pop(&mut self) -> Option<PathStep>

Pop the last step from the path.

pub fn steps(&self) -> &[PathStep]

Get the steps in this path.

pub fn len(&self) -> usize

Get the length of this path.

pub fn is_empty(&self) -> bool

Check if this path is empty.

pub fn format_with_shape(&self, shape: &'static Shape) -> String

Format this path as a human-readable string by walking the given shape.

Returns a path like outer.inner.items[3].name.

Trait Implementations

impl Clone for Path

fn clone(&self) -> Path

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Path

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

Formats the value using the given formatter.

impl Default for Path

fn default() -> Path

Returns the “default value” for a type.
