Enum PathSegment

pub enum PathSegment<'a> {
    Key(&'a str),
    Index(usize),
}

A segment in a path expression.

Variants

Key(&'a str)

A key in an object.

Index(usize)

An index in an array.

Implementations

impl<'a> PathSegment<'a>

pub fn key(arena: &'a DataArena, key: &str) -> Self

Creates a new key segment.

pub fn index(index: usize) -> Self

Creates a new index segment.

pub fn parse(arena: &'a DataArena, segment: &str) -> Self

Parses a path segment from a string.

Trait Implementations

impl<'a> Clone for PathSegment<'a>

fn clone(&self) -> PathSegment<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for PathSegment<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for PathSegment<'a>

fn eq(&self, other: &PathSegment<'a>) -> 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.
