Errors that can be returned by the Feature Management Program

Error codes are explicitly assigned to ensure stability across versions. Do not reorder variants or change their discriminant values.

Variants

Unauthorized = 0

Unauthorized access - signature verification failed

InvalidFeatureName = 1

Invalid feature name (empty or too long)

FeatureNotFound = 2

Feature not found

InvalidTimeRange = 3

Invalid time range (start time >= end time)

SerializationError = 4

Serialization error

DeserializationError = 5

Deserialization error

InvalidInstructionData = 6

Invalid instruction data

InternalError = 7

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

DuplicateFeature = 8

Duplicate feature in modification list

InvalidStorageAccount = 9

Invalid storage account (not the expected PDA)

AlreadyInitialized = 10

Storage account already initialized

NotInitialized = 11

Storage account not initialized

TimeOutOfRange = 12

start_time_ms or end_time_ms exceeds the sanity cap (MAX_TIMESTAMP_MS).

StickyCannotBecomeWindowed = 13

Existing sticky entry would become windowed (caller passed Some(end_time_ms) over an existing None).

StickyStartTimeBackward = 14

Sticky entry’s start_time_ms would move backwards.

EntryFrozen = 15

Existing entry is in its active phase; modification rejected.

StickyEntryNotRemovable = 16

Attempted to remove an existing sticky entry.

MaxFeatureCountExceeded = 17

Maximum feature count exceeded.

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 From<FeatureManagementError> for InstructionError

fn from(e: FeatureManagementError) -> Self

Converts to this type from the input type.

impl From<FeatureManagementError> for ProgramError

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)
