Enum ScriptViolation 

#[non_exhaustive]
pub enum ScriptViolation {
    UnexpectedCall {
        call_index: usize,
        purpose: &'static str,
    },
    WrongPurpose {
        call_index: usize,
        expected: &'static str,
        found: &'static str,
    },
    StepsUnused {
        remaining: usize,
        next: &'static str,
    },
}

A call the script did not anticipate, or a step it never reached.

Every variant names positions, purposes and labels — never a prompt, a scripted value or anything a user typed.

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.

UnexpectedCall

A call arrived after the script ran out of steps.

Fields

call_index: usize

Position of the call.

purpose: &'static str

Purpose the call carried.

WrongPurpose

A call arrived for another purpose than the next step expected.

Fields

call_index: usize

Position of the call.

expected: &'static str

Purpose the step expected.

found: &'static str

Purpose the call carried.

StepsUnused

The script still had steps when it was verified.

Fields

remaining: usize

How many steps are left.

next: &'static str

Label of the first unused reply.

Trait Implementations

impl Clone for ScriptViolation

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 ScriptViolation

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

Formats the value using the given formatter.

impl Display for ScriptViolation

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

Formats the value using the given formatter.

impl Eq for ScriptViolation

impl Error for ScriptViolation

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 ScriptViolation

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

Equality operator ==.

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

Inequality operator !=.
