Why a protected act, delivery or page was refused.

Every variant has a stable Self::name; none carries a payload, a credential, a resource id or a channel name, so a refusal can cross any boundary whole.

Variants

HolderUnverified

The connection proved no Lys holder, so it has no membership.

HolderKindUnknown

The admitted pass did not name its holder’s directory kind.

HolderMalformed

The verified holder’s id or kind is empty or carries control characters.

AuthorityMissing

No ACCESS-005 grant authority is installed, so no membership is current.

NotReady

The grant authority has not established its verified baseline.

Unavailable

The grant authority or the provider could not be asked, by cause.

Fields

cause: String

The stable cause, naming no response body.

Gap

The grant authority’s change feed has an uncovered interval.

Fields

after: u64

The last revision applied before the gap.

missing: u64

How many revisions are missing.

Reset

The grant log was reset; its revisions no longer compare.

ResumePending

The authority moved to a generation this index has not yet resumed.

ChangeApplying

A change or a resume is re-deciding this binding.

LogMismatch

The answer or the authority names another grant log or epoch.

ContractUnsupported

The provider answered under a contract this liminal does not speak.

Fields

contract: u32

The contract version the provider named.

AnswerSubstituted

The answer echoes a request other than the one asked: a substituted subject, resource, workspace or action.

RevisionStale

The answer reflects an older revision than the one required.

Fields

required: u64

The least revision required.

decided: Option<u64>

The revision decided at, if any.

ScopeOutsideMapping

The allowing scope is neither the mapped channel nor its workspace.

Refused

Lys refused the membership by its stable name.

Fields

refusal: String

The provider’s stable refusal name.

Held

A grant reaches the act, but only by approval.

Fields

mode: Mode

The approval the grant requires.

CapacityExceeded

The index is at its configured bound; nothing was allocated.

Fields

limit: usize

The configured bound.

IndexPoisoned

The index lock was poisoned by a panic elsewhere.

WorkspaceNotMapped

The workspace asked about is not in the product mapping.

ChannelNotMapped

The channel asked about is not in the product mapping.

CursorForeign

The continuation was issued for another question.

CursorStale

The continuation was issued at another generation or log epoch.

PageOverBound

A page exceeded its row or byte bound.

Fields

rows: u64

The rows the page carried.

bytes: u64

The encoded bytes the rows carried.

PageForeignRow

A page row answers another subject, kind, resource or workspace.

PageDuplicateRow

A page listed one row twice.

PageInconsistent

A page’s counts, completion and continuation disagree.

Implementations

impl MembershipRefusal

pub const fn holds(&self) -> bool

Whether this refusal holds rather than denies (ACCESS-006 R2): the authority or the index is not current, so a queued protected delivery waits, releasing nothing, rather than being retired. Every other refusal is a decided deny.

pub fn name(&self) -> &str

The stable machine name.

Trait Implementations

impl Clone for MembershipRefusal

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MembershipRefusal

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

Formats the value using the given formatter.

impl Display for MembershipRefusal

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

Formats the value using the given formatter.

impl Eq for MembershipRefusal

impl Error for MembershipRefusal

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for MembershipRefusal

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

Equality operator ==.

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

Inequality operator !=.
