Errors that can be returned by the Feature Management Program

Stable from this commit forward. Discriminants surface as ProgramError::Custom(u32) over the wire, so reordering or renumbering silently shifts what external decoders see. Pre-launch this enum has been compacted to fill the gaps left by the dropped sticky/windowed variants; from now on, add new variants only at the tail with the next unused discriminant.

Variants

Unauthorized = 0

Unauthorized access - signature verification failed

InvalidFeatureName = 1

Invalid feature name (empty or too long)

FeatureNotFound = 2

Feature not found

SerializationError = 3

Serialization error

DeserializationError = 4

Deserialization error

InvalidInstructionData = 5

Invalid instruction data

InternalError = 6

Internal error (e.g., mutex lock failure)

DuplicateFeature = 7

Duplicate feature in modification list

InvalidStorageAccount = 8

Invalid storage account (not the expected PDA)

AlreadyInitialized = 9

Storage account already initialized

NotInitialized = 10

Storage account not initialized

MaxFeatureCountExceeded = 11

Maximum feature count exceeded.

TooManyNames = 12

A single Enable instruction submitted more names than MAX_NAMES_PER_BATCH permits.

NoPendingTransfer = 13

AcceptAuthorityTransfer / CancelAuthorityTransfer invoked while no transfer is pending.

PendingTransferExists = 14

ProposeAuthorityTransfer invoked while a previous proposal is still outstanding. Cancel the existing proposal first.

InvalidTransferTarget = 15

ProposeAuthorityTransfer invoked with new_authority equal to the current authority. Distinct from Unauthorized — the signer IS the authority; the target of the transfer is degenerate.

ScheduleInPast = 16

ScheduleEnable invoked with a fire_at_ms at or before the current block time. A schedule must activate in the future; use Enable for immediate activation.

ScheduleTooFarOut = 17

ScheduleEnable invoked with a fire_at_ms more than MAX_SCHEDULE_HORIZON_MS past the current block time. Guards against fat-fingered far-future timestamps (e.g. seconds mistaken for millis).

RequestNotFound = 18

Cancel invoked with a request_id that has no pending entry — already fired, already cancelled, or never existed.

TooManyPendingRequests = 19

ScheduleEnable invoked while the pending set is already at MAX_PENDING_REQUESTS. Cancel or let existing schedules fire first.

RequestAlreadyExists = 20

ScheduleEnable invoked with a request_id that already has a pending entry.

PendingStateTooLarge = 21

ScheduleEnable whose new pending entry would push the serialized FeaturesState over MAX_FEATURES_STATE_SIZE. The byte budget — not MAX_PENDING_REQUESTS — is the binding cap once requests carry non-trivial batches, so this is surfaced explicitly rather than as a bare SerializationError at save time.

Trait Implementations

impl Clone for FeatureManagementError

fn clone(&self) -> FeatureManagementError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureManagementError

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

Formats the value using the given formatter.

impl Eq for FeatureManagementError

impl From<FeatureManagementError> for ProgramError

fn from(e: FeatureManagementError) -> Self

Converts to this type from the input type.

impl From<FeatureManagementError> for InstructionError

fn from(e: FeatureManagementError) -> Self

Converts to this type from the input type.

impl PartialEq for FeatureManagementError

fn eq(&self, other: &FeatureManagementError) -> 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.

impl PrintProgramError for FeatureManagementError

fn print<E>(&self)
