Struct PermissionCache 

pub struct PermissionCache { /* private fields */ }

Compact (resource, action) lookup pre-built from a user’s grants

• PUBLIC grants. The privilege check first probes this cache before falling back to the linear scan above. Invalidated on every GRANT / REVOKE / ALTER USER.

Implementations

impl PermissionCache

pub fn build(user_grants: &[Grant], public_grants: &[Grant]) -> PermissionCache

pub fn allows(&self, resource: &Resource, action: Action) -> bool

O(1) cache check. Returns true if the cache contains an exact (resource, action) match. Caller must still consult check_grant for hierarchical lookups (Schema covers Table, etc.).

pub fn is_empty(&self) -> bool
