Enum TaskError 

pub enum TaskError {
    NotFound(u64),
    InvalidState {
        number: u64,
        reason: &'static str,
    },
    Forbidden {
        number: u64,
        reason: &'static str,
    },
    Invalid(String),
    Store(String),
}

Why a write was refused. reason codes follow Hive’s (task_claimed, task_not_open, task_closed, not_submitted, self_verify, …).

Variants

NotFound(u64)

InvalidState

The task’s state does not allow the write.

Fields

number: u64

reason: &'static str

Forbidden

The actor may not make the write.

Fields

number: u64

reason: &'static str

Invalid(String)

The request is malformed (text rules, missing fields).

Store(String)

The store could not be read, locked or written.

Implementations

impl TaskError

pub fn code(&self) -> &'static str

A stable code: not_found, invalid_state, forbidden, invalid_argument, unavailable.

pub fn reason(&self) -> Option<&'static str>

The Hive-style reason, for state and right refusals.

Trait Implementations

impl Clone for TaskError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskError

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

Formats the value using the given formatter.

impl Display for TaskError

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

Formats the value using the given formatter.

impl Eq for TaskError

impl Error for TaskError

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 TaskError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
