Enum ClientError

        address: String,

Why a call did not answer what it asked for.

Variants

Unreachable

Nothing answered at the configured address.

Fields

address: String

Where this client looked.

detail: String

What happened there, in the words of whatever failed.

NoReason

This client would not send the request, because it carried no reason.

Every mutating operation carries a reason, and a call whose reason is empty is refused here rather than at the server: nothing reaches the policy, the printer or the record.

Unsendable

A value of the request could not be rendered as JSON.

Fields

detail: String

What could not be rendered, in the words of whatever refused it.

Unreadable

The supervisor answered something this client cannot read.

Fields

status: u16

The status it answered under.

detail: String

What could not be read, in the words of whatever refused it.

Refused

The supervisor will not do what it was asked, and said why.

Fields

status: u16

The status it answered under.

detail: String

What it said, in its own words.

PrinterRefused

The policy accepted the action and the machine refused it.

Fields

detail: String

What the printer said.

answer: Box<ActionAnswer>

The record of the request and the decision taken on it.

Rejected(Box<Rejection>)

The policy refused the action, and the refusal is the answer.

Trait Implementations

impl Clone for ClientError

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 ClientError

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

Formats the value using the given formatter.

impl Display for ClientError

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

Formats the value using the given formatter.

impl Error for ClientError

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 ClientError

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

Equality operator ==.

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

Inequality operator !=.
