Enum LedgerError 

pub enum LedgerError {
    UnknownEvent {
        event: String,
        known: Vec<String>,
    },
    MissingField {
        event: String,
        field: String,
    },
    Vocabulary {
        path: PathBuf,
        reason: String,
    },
    Write {
        path: PathBuf,
        reason: String,
    },
}

Why a line was not written.

Every variant is a refusal to corrupt the record, never a partial write: the line is composed and validated in full before the file is opened.

use majordomus_cli::ledger::LedgerError;
let e = LedgerError::MissingField { event: "plan_evidence".into(), field: "covers".into() };
assert_eq!(e.to_string(), "event 'plan_evidence' is missing the required field 'covers'");

Variants

UnknownEvent

The event name is not declared in share/events.yaml.

Fields

event: String

The name that was offered.

known: Vec<String>

Every name that is declared, in declaration order.

MissingField

The event is declared, but the payload omits a key the declaration requires.

Fields

event: String

The event.

field: String

The key that is required and absent.

Vocabulary

share/events.yaml could not be read or does not parse.

Fields

path: PathBuf

The file.

reason: String

What is wrong.

Write

The line was composed and the file could not be appended to.

Fields

path: PathBuf

The ledger.

reason: String

What the filesystem said.

Trait Implementations

impl Clone for LedgerError

fn clone(&self) -> LedgerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LedgerError

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

Formats the value using the given formatter.

impl Display for LedgerError

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

Formats the value using the given formatter.

impl Eq for LedgerError

impl Error for LedgerError

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 LedgerError

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