Struct TestError 

pub struct TestError { /* private fields */ }

Test failure value — defined in rustdv-methodology since step 4, because Component::run returns it and the UVM crate sits below this one (D46/D47). Re-exported so ::rustdv::TestError is unchanged.

Implementations

impl TestError

pub fn new(msg: impl Into<String>) -> TestError

An unclassified failure — the common case for a check that failed.

pub fn with_kind(msg: impl Into<String>, kind: &'static str) -> TestError

A failure with a cause the runner can match against expect_error. Kinds are stable strings; see crate::config::ConfigError::kind.

pub fn message(&self) -> &str

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

The machine-readable cause, if this failure has one.

Trait Implementations

impl Clone for TestError

fn clone(&self) -> TestError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TestError

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

Formats the value using the given formatter.

impl Display for TestError

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

Formats the value using the given formatter.

impl Error for TestError

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 From<&str> for TestError

fn from(s: &str) -> TestError

Converts to this type from the input type.

impl From<ConfigError> for TestError

Configuration failures keep their cause, so ? in a test body still lets expect_error distinguish “nothing was set” from “wrong type”.

fn from(e: ConfigError) -> TestError

Converts to this type from the input type.

impl From<HandleError> for TestError

fn from(e: HandleError) -> TestError

Converts to this type from the input type.

impl From<SeqError> for TestError

fn from(e: SeqError) -> TestError

Converts to this type from the input type.

impl From<String> for TestError

fn from(s: String) -> TestError

Converts to this type from the input type.

impl From<TaskError> for TestError

fn from(e: TaskError) -> TestError

Converts to this type from the input type.

impl From<ValueError> for TestError

fn from(e: ValueError) -> TestError

Converts to this type from the input type.
