Struct FieldPath 

pub struct FieldPath { /* private fields */ }

Exact object-field path. An empty path selects the root value.

Implementations

impl FieldPath

pub fn new<I, S>(segments: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Creates a path from exact object field names.

pub fn field(name: impl Into<String>) -> Self

Creates a single-field path.

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

Returns the exact path segments.

pub fn resolve<'value>(&self, root: &'value Value) -> Option<&'value Value>

Resolves this path, returning None for a missing field or traversal through a non-object value.

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

Formats the value using the given formatter.

impl Default for FieldPath

fn default() -> FieldPath

Returns the “default value” for a type.

impl Eq for FieldPath

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

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.
