Enum OptionKey 

pub enum OptionKey {
    Value(Value),
    None,
}

Key for matching option branches in BranchStep.

OptionKey is used to route traversers to specific branches based on computed values. It supports two variants:

• Value(Value) - Match a specific value
• None - Default fallback when no other option matches

Example

use interstellar::traversal::branch::OptionKey;

// Create keys from various types
let key1 = OptionKey::from("person");
let key2 = OptionKey::from(42i64);
let key3 = OptionKey::none();

Variants

Value(Value)

Match a specific value.

None

Default fallback (Pick.none in Gremlin).

Implementations

impl OptionKey

pub fn value<T: Into<Value>>(v: T) -> Self

Create an OptionKey from any type that can be converted to Value.

Example

use interstellar::traversal::branch::OptionKey;

let key = OptionKey::value("person");

pub fn none() -> Self

Create a None option key (default fallback).

Example

use interstellar::traversal::branch::OptionKey;

let key = OptionKey::none();

Trait Implementations

impl Clone for OptionKey

fn clone(&self) -> OptionKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionKey

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

Formats the value using the given formatter.

impl From<&str> for OptionKey

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for OptionKey

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Value> for OptionKey

fn from(v: Value) -> Self

Converts to this type from the input type.

impl From<bool> for OptionKey

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<i32> for OptionKey

fn from(n: i32) -> Self

Converts to this type from the input type.

impl From<i64> for OptionKey

fn from(n: i64) -> Self

Converts to this type from the input type.

impl PartialEq for OptionKey

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