Struct TenantCache 

#[non_exhaustive]
pub struct TenantCache { /* private fields */ }

Cache facade permanently bound to one authenticated tenant context.

Every operation derives the backend key from the immutable tenant identity. The wrapper intentionally has no global flush; callers may only forget explicit keys inside their tenant namespace.

Implementations

impl TenantCache

pub fn from_context(cache: Cache, context: &TenantContext) -> Self

Binds a cache to a tenant already validated by authentication.

pub fn tenant_id(&self) -> &str

Returns the authenticated tenant identifier bound to this instance.

pub fn namespaced_key(&self, logical_key: &str) -> Result<String, CacheError>

Returns the canonical backend key within this instance’s tenant namespace.

The key is tenants:<tenant>:<logical_key>. In the tenant segment % is written as %25 and : as %3A, so a logical key containing : can never alias another tenant’s namespace.

pub async fn get( &self, logical_key: &str, ) -> Result<Option<Arc<String>>, CacheError>

Retrieves a value only from this instance’s tenant namespace.

pub async fn put( &self, logical_key: &str, value: &str, ttl_secs: Option<u64>, ) -> Result<(), CacheError>

Stores a value only inside this instance’s tenant namespace.

pub async fn has(&self, logical_key: &str) -> Result<bool, CacheError>

Checks for a value only inside this instance’s tenant namespace.

pub async fn forget(&self, logical_key: &str) -> Result<(), CacheError>

Removes a value only from this instance’s tenant namespace.

pub async fn remember<F, Fut>( &self, logical_key: &str, ttl_secs: u64, compute: F, ) -> Result<Arc<String>, CacheError>

where F: FnOnce() -> Fut, Fut: Future<Output = Result<String, CacheError>>,

Retrieves a tenant-scoped value or computes and caches it.

Trait Implementations

impl Clone for TenantCache

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
