Struct CredentialCache 

pub struct CredentialCache { /* private fields */ }

TTL-based credential cache for avoiding repeated LDAP binds.

Stores hashed credentials with expiry timestamps based on tick counts (no floating point).

Implementations

impl CredentialCache

pub fn new(ttl_ticks: u64, max_entries: usize) -> Self

Create a new credential cache.

ttl_ticks is the number of timer ticks before an entry expires. max_entries limits the cache size.

pub fn lookup( &self, username: &str, password_hash: &[u8; 32], current_tick: u64, ) -> Option<&str>

Check if a cached credential exists and is still valid.

Returns the bind DN if the password hash matches.

pub fn store( &mut self, username: &str, password_hash: [u8; 32], bind_dn: &str, current_tick: u64, )

Store a credential in the cache.

pub fn purge_expired(&mut self, current_tick: u64)

Remove expired entries.

pub fn remove(&mut self, username: &str)

Remove a specific entry.

pub fn len(&self) -> usize

Get the number of cached entries.

pub fn is_empty(&self) -> bool

Check if the cache is empty.

pub fn clear(&mut self)

Clear all entries.
