Struct ErrorPath 

pub struct ErrorPath { /* 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() -> Path

Create a new empty path.

pub fn with_capacity(capacity: usize) -> Path

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.

impl Path

pub fn to_diagnostic( &self, shape: &'static Shape, message: impl Into<String>, help: Option<String>, ) -> PathDiagnostic

Create a miette diagnostic that shows the full type hierarchy with each step highlighted.

This provides rich terminal output with:

• Each type in the path shown as a separate code block
• The relevant field/variant highlighted in each type
• Optional help text

pub fn format_pretty( &self, shape: &'static Shape, message: impl Into<String>, help: Option<String>, ) -> String

Format this path with rich pretty-printing, showing the type structure with the error location highlighted.

Returns the formatted diagnostic as a string for display.

pub fn format_pretty_no_color( &self, shape: &'static Shape, message: impl Into<String>, help: Option<String>, ) -> String

Format with explicit color control (for testing)

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<(), Error>

Formats the value using the given formatter.

impl Default for Path

fn default() -> Path

Returns the “default value” for a type.
