Enum HarnessError 

#[non_exhaustive]
pub enum HarnessError {
    Setup {
        message: String,
    },
    UnknownWorkflow {
        workflow: String,
    },
    NoBlockingCard {
        case: String,
    },
    Store {
        message: String,
    },
}

Why a sample could not be set up or started.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Setup

The world could not be built.

Fields

message: String

What went wrong.

UnknownWorkflow

The item names a workflow the harness did not register.

Fields

workflow: String

The workflow key.

NoBlockingCard

The item answers a card, and the case has none.

Fields

case: String

The case, as workflow/case_id.

Store

The card store could not be read.

Fields

message: String

What the store said.

Implementations

impl HarnessError

pub fn setup(message: impl Into<String>) -> Self

A setup failure with a message.

Trait Implementations

impl Clone for HarnessError

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 HarnessError

impl Eq for HarnessError

impl Error for HarnessError

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 HarnessError

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

Equality operator ==.

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

Inequality operator !=.
