Struct RegexLabeler 

pub struct RegexLabeler { /* private fields */ }

A labeler that uses regular expressions for matching on resource attributes.

Implementations

impl RegexLabeler

pub fn new( kind: impl Into<String>, field: impl Into<String>, output: impl Into<String>, table: Vec<(String, Regex)>, ) -> Self

Create a regex-based labeler.

• kind: resource kind this applies to (e.g., “Host”)
• field: attribute to read from (e.g., “name”)
• output: attribute to write labels to (e.g., “nameLabels”)
• table: vector of (label, regex) pairs

Configure field and output as distinct attributes so repeated application remains idempotent. field reads the resource attribute map; it does not expose canonical entity fields. In particular, an attribute named id is not the canonical Resource::id value during labeling. Use a custom Labeler that reads Resource::id when labels must derive from the resource identity.

Trait Implementations

impl Clone for RegexLabeler

fn clone(&self) -> RegexLabeler

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegexLabeler

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

Formats the value using the given formatter.

impl Labeler for RegexLabeler

fn applies_to(&self, kind: &str) -> bool

Returns true if this labeler applies to resources of the given kind.

fn apply(&self, res: &mut Resource)

Mutates the resource by injecting derived attributes (e.g., sets of labels).
