Expand description

Trait for permission cache backends

Implementations must be Send + Sync for use across async tasks.

Required Methods§

Source

fn get<'life0, 'life1, 'async_trait>( &'life0 self, user_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<HashSet<Permission>>, CacheError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get cached permissions for a user

Returns None if the user’s permissions are not cached or have expired.

Source

fn set<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, user_id: &'life1 str, permissions: &'life2 HashSet<Permission>, ttl_seconds: u64, ) -> Pin<Box<dyn Future<Output = Result<(), CacheError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Cache permissions for a user with a TTL

Source

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, user_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), CacheError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete cached permissions for a specific user

Source

fn clear<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), CacheError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Clear all cached permissions

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
