Struct SettingsCache 

pub struct SettingsCache { /* private fields */ }

LRU cache for settings values. Uses Mutex because LruCache::get mutates internal recency state.

Implementations

impl SettingsCache

pub fn new(capacity: usize) -> Self

pub fn get(&self, tn_id: TnId, key: &str) -> Option<SettingValue>

pub fn put(&self, tn_id: TnId, key: String, value: SettingValue)

pub fn clear(&self)

Invalidate all cached settings

pub fn invalidate_key(&self, key: &str)

Invalidate cached entries for a specific key across all tenants (typically called after a global setting changes, so each tenant re-resolves through the new global default on next read).
