Enum AuditError 

pub enum AuditError {
    Io {
        path: String,
        source: Error,
    },
    Malformed {
        line: usize,
        source: Error,
    },
    Frame {
        path: String,

    },
    Unframed {

        line: usize,
        what: String,
    },
}

What went wrong with the chain.

Variants

Io

The file could not be read, created or written.

Fields

path: String

Which file.

source: Error

The underlying failure.

Malformed

A line in the file is not an entry.

Fields

line: usize

1-based line number.

source: Error

What serde said.

Frame

The line could not be framed into the transaction log, so it was not written down at all. Deliberately not best-effort: a trail whose file and whose log disagree is worse than one missing entry, because the missing entry is announced and the disagreement is not.

Fields

path: String

Which file.

detail: String

What the log said.

Unframed

This chain was asked to be the REPLICATED trail and cannot be (AuditChain::open_framed). Never silent: the caller says so out loud and opens an unframed chain instead.

Fields

path: String

Which file.

why: String

Why not, in a sentence an operator can act on.

NotOriginated

The box FOLLOWS (a twin, or a box being restored): it originates nothing into the replicated trail it holds for its primary, so nothing was written (Recorded::NotOriginated through AuditChain::append). Not a fault: the caller’s log line is the record.

Fields

path: String

Which file.

Broken

The chain does not hold. This is the finding, not a fault.

Fields

seq: u64

The seq the entry claims.

line: usize

1-based line number.

what: String

Which invariant failed, in a sentence an operator can act on.

Trait Implementations

impl Debug for AuditError

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

Formats the value using the given formatter.

impl Display for AuditError

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

Formats the value using the given formatter.

impl Error for AuditError

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.
