Enum IntegrityError 

#[non_exhaustive]
pub enum IntegrityError {
    Mmr(MmrError),
    MalformedRoot {
        leaf_count_hint: u64,
        source: Error,
    },
    SignatureInvalid {
        leaf_count: u64,
    },
    RootMismatch {
        leaf_count: u64,
        expected_root_hex: String,
        computed_root_hex: String,
    },
}

Failures from extending, signing, or verifying a partition’s MMR.

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.

Mmr(MmrError)

The underlying MMR operation failed (lock poisoned, proof error).

MalformedRoot

A signed-root marker’s payload was not the JSON SignedRoot this module writes — a corrupted or foreign event landed under the reserved kind.

Fields

leaf_count_hint: u64

Running leaf count at the point the malformed marker was found, for locating it in the replay.

source: Error

The JSON decode error.

SignatureInvalid

A persisted root’s ed25519 signature does not verify under the expected signer public key — the marker was forged, or signed by a different key than the caller trusts.

Fields

leaf_count: u64

The root’s claimed leaf count.

RootMismatch

The recomputed MMR root (or leaf count) at a checkpoint does not match what was signed — the tamper-evidence violation this whole module exists to catch.

Fields

leaf_count: u64

Leaf count at the point of the mismatch.

expected_root_hex: String

The root the signed marker claims.

computed_root_hex: String

The root replay actually computed.

Trait Implementations

impl Debug for IntegrityError

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

Formats the value using the given formatter.

impl Display for IntegrityError

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

Formats the value using the given formatter.

impl Error for IntegrityError

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 From<MmrError> for IntegrityError

fn from(source: MmrError) -> IntegrityError

Converts to this type from the input type.
