Enum Segment 

#[non_exhaustive]
pub enum Segment {
    Field(String),
    Index(i64),
    Iterate,
    Slice {
        start: Option<i64>,
        end: Option<i64>,
        step: Option<i64>,
    },
    Wildcard,
    RecursiveDescent(String),
}

A single segment of a navigation path.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Field(String)

필드 접근 (.name)

Index(i64)

배열 인덱스 접근 ([0], [-1])

Trait Implementations

impl Clone for Segment

fn clone(&self) -> Segment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Segment

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

Formats the value using the given formatter.

impl PartialEq for Segment

fn eq(&self, other: &Segment) -> 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.
