Enum ChainVerifyError 

#[non_exhaustive]
pub enum ChainVerifyError {
    BrokenLink {
        entry_index: usize,
        expected_hash: String,
        stored_hash: String,
    },
    MissingChainHash {
        entry_index: usize,

    InvalidEntry {

    },
}

Error returned by verify_chain when the chain is broken.

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.

BrokenLink

A computed hash does not match the stored chain_hash at this entry.

Fields

entry_index: usize

Zero-based index of the first broken entry.

expected_hash: String

The hash we computed from the chain.

stored_hash: String

The chain_hash stored in the entry.

MissingChainHash

An entry could not be parsed (missing or invalid chain_hash field).

Fields

entry_index: usize

Zero-based index of the malformed entry.

InvalidEntry

An audit entry is not a JSON object.

Every entry produced by the audit logger is a JSON object. If this variant is returned the supplied entries are malformed or have been tampered with.

Fields

entry_index: usize

Zero-based index of the malformed entry.

Trait Implementations

impl Debug for ChainVerifyError

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

Formats the value using the given formatter.

impl Display for ChainVerifyError

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

Formats the value using the given formatter.

impl Error for ChainVerifyError

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.
