Struct LabelRegistryBuilder 

pub struct LabelRegistryBuilder { /* private fields */ }

Builder for creating a LabelRegistry with labelers.

This uses a builder pattern to ensure labelers are properly initialized before the registry is used.

Example

use std::sync::Arc;
use treetop_core::{LabelRegistryBuilder, RegexLabeler};
use regex::Regex;

let registry = LabelRegistryBuilder::new()
    .add_labeler(Arc::new(RegexLabeler::new(
        "Host",
        "name",
        "nameLabels",
        vec![("prod".to_string(), Regex::new(r"\.prod\.").unwrap())],
    )))
    .build();

Implementations

impl LabelRegistryBuilder

pub fn new() -> Self

Create a new, empty label registry builder.

pub fn add_labeler(self, labeler: Arc<dyn Labeler>) -> Self

Add a labeler to the registry.

This can be called repeatedly to build up a registry before build().

pub fn build(self) -> LabelRegistry

Build the label registry.

Consumes the builder and returns an initialized registry ready to use with PolicyEngine::with_label_registry().

Trait Implementations

fn default() -> Self

Returns the “default value” for a type.
