Trait Implementations

impl AccessControl for AccessControlList

type Id = Vec<u8>

Native identity type used by this provider.

fn load<M>(mm: &mut MemoryManager<M>) -> MemoryResult<Self>

where M: MemoryProvider,

Loads ACL state from persisted memory.

fn granted( &self, id: &Self::Id, table: TableFingerprint, perm: TablePerms, ) -> bool

Returns whether id is granted perm on table.

fn granted_admin(&self, id: &Self::Id) -> bool

Returns whether id carries the admin bypass flag.

fn granted_manage_acl(&self, id: &Self::Id) -> bool

Returns whether id carries the manage_acl flag.

fn granted_migrate(&self, id: &Self::Id) -> bool

Returns whether id carries the migrate flag.

fn grant<M>( &mut self, id: Self::Id, grant: PermGrant, mm: &mut MemoryManager<M>, ) -> MemoryResult<()>

where M: MemoryProvider,

Applies a grant to id, creating the entry if missing.

fn revoke<M>( &mut self, id: &Self::Id, revoke: PermRevoke, mm: &mut MemoryManager<M>, ) -> MemoryResult<()>

where M: MemoryProvider,

Applies a revoke to id. No-op if id is not present.

fn remove_identity<M>( &mut self, id: &Self::Id, mm: &mut MemoryManager<M>, ) -> MemoryResult<()>

where M: MemoryProvider,

Removes id entirely from the ACL.

fn perms(&self, id: &Self::Id) -> IdentityPerms

Returns the IdentityPerms currently held by id, or the default (no perms) if id is unknown.

fn identities(&self) -> Vec<(Self::Id, IdentityPerms)>

Returns every identity in the ACL together with its perms.

impl Clone for AccessControlList

fn clone(&self) -> AccessControlList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccessControlList

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AccessControlList

fn default() -> AccessControlList

Returns the “default value” for a type.

impl Encode for AccessControlList

const SIZE: DataSize = DataSize::Dynamic

The size characteristic of the data type.

const ALIGNMENT: PageOffset = DEFAULT_ALIGNMENT

The alignment requirement in bytes for the data type.

fn encode(&self) -> Cow<'_, [u8]>

Encodes the data type into a vector of bytes.

fn decode(data: Cow<'_, [u8]>) -> MemoryResult<Self>

where Self: Sized,

Decodes the data type from a slice of bytes.

fn size(&self) -> MSize

Returns the size in bytes of the encoded data type.

impl PartialEq for AccessControlList

fn eq(&self, other: &AccessControlList) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
