Function matches_selector 

pub fn matches_selector(
    selector: &LabelSelector,
    labels: &BTreeMap<String, String>,
) -> bool

Check if a set of labels matches a label selector.

This function implements the Kubernetes label selector matching logic:

• All matchLabels entries must be present with exact values
• All matchExpressions requirements must be satisfied
• An empty selector matches everything
• A selector with no matchLabels and no matchExpressions matches everything

Arguments

• selector - The label selector to evaluate
• labels - The labels to match against

Returns

true if the labels match the selector, false otherwise

Examples

use std::collections::BTreeMap;
use bindy::crd::LabelSelector;
use bindy::selector::matches_selector;

let mut labels = BTreeMap::new();
labels.insert("app".to_string(), "web".to_string());
labels.insert("env".to_string(), "prod".to_string());

let mut match_labels = BTreeMap::new();
match_labels.insert("app".to_string(), "web".to_string());

let selector = LabelSelector {
    match_labels: Some(match_labels),
    match_expressions: None,
};

assert!(matches_selector(&selector, &labels));
