Function parse_rotation_annotations 

pub fn parse_rotation_annotations(
    annotations: &BTreeMap<String, String>,
) -> Result<(DateTime<Utc>, Option<DateTime<Utc>>, u32)>

Parse rotation tracking annotations from a Kubernetes Secret.

Extracts the created_at, rotate_at, and rotation_count annotations from a Secret’s metadata.

Arguments

• annotations - Secret annotations map

Returns

A tuple of:

• created_at: Timestamp when the key was created or last rotated
• rotate_at: Optional timestamp when rotation is due (None if rotation disabled)
• rotation_count: Number of times the key has been rotated

Errors

Returns an error if:

• The created-at annotation is missing
• Any timestamp cannot be parsed as ISO 8601
• The rotation-count annotation cannot be parsed as u32

Examples

use std::collections::BTreeMap;
use bindy::bind9::rndc::parse_rotation_annotations;

let mut annotations = BTreeMap::new();
annotations.insert(
    "bindy.firestoned.io/rndc-created-at".to_string(),
    "2025-01-26T10:00:00Z".to_string()
);
annotations.insert(
    "bindy.firestoned.io/rndc-rotate-at".to_string(),
    "2025-02-25T10:00:00Z".to_string()
);
annotations.insert(
    "bindy.firestoned.io/rndc-rotation-count".to_string(),
    "5".to_string()
);

let (created_at, rotate_at, count) = parse_rotation_annotations(&annotations).unwrap();
assert_eq!(count, 5);
