Struct Path 

pub struct Path {
    pub shape: &'static Shape,
    pub steps: Vec<PathStep>,
}

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.

Fields

shape: &'static Shape

The root Shape from which this path originates.

steps: Vec<PathStep>

The sequence of PathSteps representing navigation through the type structure.

Implementations

impl Path

pub const fn new(shape: &'static Shape) -> Self

Create a new empty path.

pub fn with_capacity(shape: &'static Shape, 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 const fn len(&self) -> usize

Get the length of this path.

pub const fn is_empty(&self) -> bool

Check if this path is empty.

pub fn format(&self) -> String

Format this path as a human-readable string using the stored root shape.

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

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.

pub fn resolve_leaf_field( &self, shape: &'static Shape, ) -> Option<&'static Field>

Resolve the field at the end of this path, if the path ends at a struct field.

This navigates through the given shape following each step in the path, and returns the Field if the final step is a PathStep::Field.

This is useful for accessing field metadata like attributes when handling errors that occur at a specific field location.

Returns

• Some(&Field) if the path ends at a struct field
• None if the path is empty, doesn’t end at a field, or navigation fails

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 Display for Path

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

Formats the value using the given formatter.

impl Hash for Path

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 Ord for Path

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 PartialEq for Path

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 PartialOrd for Path

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.
