Enum TrialError 

pub enum TrialError {
    Name(NameError),
    EmptyElementAssignments {
        element: String,
    },
    MisaddressedValue {
        expected: ParameterName,
        actual: ParameterName,
    },
}

Errors from Trial / Assignments construction.

Separate from the broader crate Error so the construction path can have a narrow, matchable type. Wrapped by Error::Trial via #[from].

Variants

Name(NameError)

A name newtype failed validation.

EmptyElementAssignments

An element’s inner parameter map is empty.

Fields

element: String

The offending element name.

MisaddressedValue

A value is keyed under a parameter name that doesn’t match its own Provenance.parameter.

Fields

expected: ParameterName

The outer-map key this value was stored under.

actual: ParameterName

The name the value’s provenance records.

Trait Implementations

impl Debug for TrialError

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

Formats the value using the given formatter.

impl Display for TrialError

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

Formats the value using the given formatter.

impl Error for TrialError

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<NameError> for TrialError

fn from(source: NameError) -> Self

Converts to this type from the input type.

impl From<TrialError> for Error

fn from(source: TrialError) -> Self

Converts to this type from the input type.

impl PartialEq for TrialError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
