Enum PathSegment 

pub enum PathSegment {
    Field(String),
    Index(usize),
    Key(String),
}

A segment of a field path.

Paths can navigate through:

• Named fields in structs
• Numeric indices in arrays/vectors
• String keys in maps

Variants

Field(String)

A named field (e.g., user in user.email)

Index(usize)

An array/vector index (e.g., [0] in items[0].name)

Key(String)

A map key (e.g., ["key"] in metadata["key"].value)

Implementations

impl PathSegment

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

Create a field segment

pub fn index(idx: usize) -> PathSegment

Create an index segment

pub fn key(key: impl Into<String>) -> PathSegment

Create a key segment

Trait Implementations

impl Clone for PathSegment

fn clone(&self) -> PathSegment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathSegment

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PathSegment

fn deserialize<__D>( __deserializer: __D, ) -> Result<PathSegment, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PathSegment

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

Formats the value using the given formatter.

impl Hash for PathSegment

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 PartialEq for PathSegment

fn eq(&self, other: &PathSegment) -> 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 Serialize for PathSegment

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
