Variants

IssueNotFound

No heading in the corpus carries this id.

Fields

id: String

ClaimConflict

Another identity already holds the issue.

Fields

id: String

The issue that is already claimed.

holder: String

Who holds it.

claimed_at: Option<String>

When the claim was stamped, if the heading recorded it.

BlockerCycle

The edge would close a loop in the blocker graph.

Fields

blocker: String

The prospective prerequisite.

issue: String

The issue that would wait on it.

InvalidState

The issue is in a state that cannot be claimed.

Fields

id: String

The issue that was refused.

state: String

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

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
