Struct FieldPath 

pub struct FieldPath { /* private fields */ }

A path through the type tree to a field.

Implementations

impl FieldPath

pub fn empty() -> FieldPath

Create an empty path (root level).

pub fn depth(&self) -> usize

Get the depth of this path.

pub fn push_field(&self, name: &'static str) -> FieldPath

Push a field segment onto the path.

pub fn push_variant( &self, field_name: &'static str, variant_name: &'static str, ) -> FieldPath

Push a variant segment onto the path.

pub fn parent(&self) -> FieldPath

Get the parent path (all segments except the last).

pub fn segments(&self) -> &[PathSegment]

Get the segments of this path.

pub fn last(&self) -> Option<&PathSegment>

Get the last segment, if any.

Trait Implementations

impl Clone for FieldPath

fn clone(&self) -> FieldPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldPath

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

Formats the value using the given formatter.

impl Display for FieldPath

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

Formats the value using the given formatter.

impl Hash for FieldPath

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 FieldPath

fn cmp(&self, other: &FieldPath) -> 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 FieldPath

fn eq(&self, other: &FieldPath) -> 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 FieldPath

fn partial_cmp(&self, other: &FieldPath) -> 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.
