Canonical error codes returned across the Confium FFI surface.

These mirror confium_core::error::ErrorCode exactly — same names, same numeric values — so a plugin’s status code is meaningful to the loader without a translation layer. (The cross-crate link is not resolvable here because confium-api does not depend on confium-core.)

Never reorder or renumber existing variants: they are wire-stable. New variants may only be appended.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UNKNOWN = 1

NULL_POINTER = 2

INVALID_UTF8 = 3

WRONG_TYPE = 10

VALUE_NOT_FOUND = 11

INSUFFICIENT_BUFFER = 12

UNKNOWN_PROVIDER = 13

PLUGIN_LOAD_FAILED = 20

PLUGIN_SYMBOL_ERROR = 21

PLUGIN_INITIALIZATION_FAILED = 22

PLUGIN_INTERFACE_VERSION_UNSUPPORTED = 23

PLUGIN_NAME_COLLISION = 24

PLUGIN_MISSING_INTERFACE = 25

PLUGIN_INTERNAL_ERROR = 26

UNSUPPORTED_ALGORITHM = 50

PLUGIN_GENERIC = 27

The plugin encountered an error that does not map to one of the canonical codes. The plugin should still produce a useful Display string for logging, but the loader has no typed recovery path.

Implementations

impl ErrorCode

pub fn into_wire(self) -> u32

Numeric wire value the loader expects. Equal to the discriminant.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorCode

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Eq for ErrorCode

impl From<ErrorCode> for u32

fn from(code: ErrorCode) -> Self

Converts to this type from the input type.

impl PartialEq for ErrorCode

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