Struct IdGenerator 

pub struct IdGenerator { /* private fields */ }

Thread-safe unique ID generator for ARIA attribute cross-references.

Every interactive component needs unique, stable IDs for ARIA attributes like aria-controls, aria-labelledby, and aria-describedby.

IDs are generated with a configurable prefix and an atomic counter, producing values like "stratum-btn-001", "stratum-dialog-002".

Implementations

impl IdGenerator

pub fn new(prefix: impl Into<String>) -> Self

Create a new ID generator with the given prefix.

Example

use stratum_core::IdGenerator;
let id_gen = IdGenerator::new("btn");
let id = id_gen.next();
assert!(id.starts_with("stratum-btn-"));

pub fn next(&self) -> String

Generate the next unique ID.

pub fn paired(&self) -> (String, String)

Generate a paired set of IDs for label + target relationships.

Returns (label_id, target_id) — useful for aria-labelledby and aria-controls relationships.

pub fn group(&self, suffixes: &[&str]) -> Vec<String>

Generate a set of related IDs for multi-part components.

For example, a Disclosure needs a trigger ID and content ID.

pub fn current_count(&self) -> u64

Get the current counter value (for testing).
