All decode / validation errors raised by the serialize module, plus a small number of construction-time errors.

Variants

EmptyData

InvalidObjectType(u8)

InvalidMagic

UnsupportedObjectVersion

UnexpectedEof

TrailingData

TooManyEntries

InvalidEntryName

InvalidEntryMode(u8)

InvalidEntryOrder

TooManyParents

TooManySources

TagNameInvalid

TagTargetTypeInvalid(u8)

InvalidSourceOrder

TooManyChunks

UnknownIdentityKind(u8)

InvalidIdentity

IdentityTooLarge

OversizePayload

A length-prefixed field exceeded the wire-format u32 cap. Only raised by serialise; deserialise can never observe a value larger than u32::MAX because it reads the prefix first.

Fields

field: &'static str

len: usize

RngFailure

Underlying secure-randomness source could not produce bytes.

SignatureInvalid

Signature verification failed (bad signature, wrong key, tampered input, or wrong domain). The Ed25519 layer never tells us why.

InvalidPublicKey

Public-key bytes do not decode to a valid Edwards point.

InsecureKeyPermissions

Key file on disk has a permission bit set that allows non-owner access (POSIX mode & 0o077 != 0). Refuses to load.

Fields

actual: u32

InsecureKeyOwner

Key file is owned by a different uid than the calling process. Could mean a planted file from a tar extraction or a malicious bind mount. Refuse with the observed uid for diagnostics.

Fields

actual: u32

euid: u32

InsecureKeyDir

Parent directory of the key file is group/world-accessible. .mkit/keys/ MUST be 0700 to keep inotify-style swap attacks out of reach.

Fields

actual: u32

KeyPathIsSymlink(String)

Key path resolves through a symlink. We refuse symlinks at the open(2) layer (O_NOFOLLOW) — this variant fires when the kernel returns ELOOP. An attacker who can pre-create the path as a symlink could otherwise redirect us to a key they control.

InvalidKeyLength

Key file length is not exactly 32 bytes.

Fields

actual: usize

KeyIo(String)

Wrapped I/O error from key load/save. Boxed to keep MkitError variant size small.

DeltaLengthOverflow

Delta encode input exceeds the v1 wire-format u32 length cap (base or result > 4 GiB - 1). SPEC-PACKFILE holds individual payloads under this bound, so this is a caller-programming error, not a normal runtime condition — but saturating instead of erroring silently produced a stream decode() would reject with a misleading “length mismatch”.

Fields

field: &'static str

len: usize

Trait Implementations

impl Clone for MkitError

fn clone(&self) -> MkitError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MkitError

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

Formats the value using the given formatter.

impl Display for MkitError

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

impl Eq for MkitError

impl Error for MkitError

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 MkitError

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