Enum Tag 

pub enum Tag {
    Simple(String),
    Pair(String, String),
    List(String, Vec<String>),
}

Tag enum supporting Simple, Pair, and List formats

Variants

Simple(String)

Simple tag: single word (e.g., “finance”)

Pair(String, String)

Pair tag: key:value format (e.g., “Environment:Dev”)

List(String, Vec<String>)

List tag: key:[value1, value2, …] format (e.g., “SecondaryDomains:[XXXXX, PPPP]”)

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Tag

fn deserialize<D>( deserializer: D, ) -> Result<Tag, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Tag

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

Serialize Tag enum to string format

Formats:

• Simple: “finance”
• Pair: “Environment:Dev”
• List: “SecondaryDomains:[XXXXX, PPPP]”

impl FromStr for Tag

fn from_str(s: &str) -> Result<Tag, <Tag as FromStr>::Err>

Parse a tag string into a Tag enum with auto-detection

Parsing logic:

• No colon = Simple tag
• Single colon (not followed by bracket, and no more colons) = Pair tag
• Colon followed by bracket = List tag
• Multiple colons without brackets = Simple tag (malformed, graceful degradation)

Malformed tags are treated as Simple tags (graceful degradation)

type Err = ()

The associated error which can be returned from parsing.

impl Hash for Tag

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 Tag

fn eq(&self, other: &Tag) -> 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 Tag

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.

impl Eq for Tag

impl StructuralPartialEq for Tag
