Struct PermissionCache 

pub struct PermissionCache<K: Eq + Hash> { /* private fields */ }

Generic permission cache that works for any hashable key type. Eliminates duplication between file-based and tool-based caches.

Implementations

impl<K: Eq + Hash> PermissionCache<K>

pub fn new() -> Self

Create new permission cache

pub fn get_permission<Q>(&mut self, key: &Q) -> Option<PermissionGrant>

where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

Check if we have a cached permission for this key

pub fn cache_grant(&mut self, key: K, grant: PermissionGrant)

Cache a permission grant

pub fn invalidate<Q>(&mut self, key: &Q)

where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

Invalidate permission for a key

pub fn clear_temporary_denials(&mut self)

Clear only temporary denials (for retries)

pub fn clear(&mut self)

Clear all cached permissions

pub fn stats(&self) -> PermissionCacheStats

Get cache statistics

pub fn is_denied<Q>(&self, key: &Q) -> bool

where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

Check if key is denied by policy (not execution failure)

pub fn is_temporarily_denied<Q>(&self, key: &Q) -> bool

where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

Check if key has a temporary denial (execution failure, not policy)

pub fn can_use_cached<Q>(&self, key: &Q) -> bool

where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

Check if we can use cached permission without prompting.

Once grants are included so that a single user approval persists for the duration of the session — without this, every identical tool call would re-prompt even after the user already said “yes”.

impl PermissionCache<String>

Extension methods for ToolPermissionCache to maintain API compatibility

pub fn cache_grant_tool( &mut self, tool_name: impl Into<String>, grant: PermissionGrant, )

Cache a permission grant for a tool (accepts impl Into<String>)

impl PermissionCache<String>

pub fn get(&mut self, key: &str) -> Option<bool>

pub fn put(&mut self, key: &str, allowed: bool, _reason: &str)

Formats the value using the given formatter.

impl<K: Eq + Hash> Default for PermissionCache<K>

fn default() -> Self
