Struct ChallengeManager 

pub struct ChallengeManager { /* private fields */ }

Manages pending ACME HTTP-01 challenges

When the ACME server needs to validate domain ownership, it requests a specific URL path. This manager stores the token -> key authorization mapping so the proxy can serve the correct response.

Thread Safety

Uses DashMap for lock-free concurrent access from multiple request handling threads.

Implementations

impl ChallengeManager

pub fn new() -> Self

Create a new challenge manager

pub fn add_challenge(&self, token: &str, key_authorization: &str)

Register a pending challenge

Called when starting the ACME challenge flow. The key authorization will be served when the ACME server requests the challenge URL.

Arguments

• token - The challenge token from the ACME server
• key_authorization - The response to return (token + account key thumbprint)

pub fn remove_challenge(&self, token: &str)

Remove a completed or expired challenge

Called after the challenge is validated or times out.

pub fn get_response(&self, token: &str) -> Option<String>

Get the key authorization response for a challenge token

Returns Some(key_authorization) if the token is registered, None otherwise.

pub fn extract_token(path: &str) -> Option<&str>

Check if this is an ACME challenge request path

Returns Some(token) if the path matches the challenge prefix, None otherwise.

pub fn pending_count(&self) -> usize

Get the number of pending challenges

pub fn clear(&self)

Clear all pending challenges

Called during shutdown or reset.
