Enum Diagnostic 

#[non_exhaustive]
pub enum Diagnostic {
    InvalidOperation {
        operation: String,
        location: String,
        reason: &'static str,
    },
}

Structured diagnostics and recovery categories for failed dialect operations. Structured diagnostics and recovery categories for failed dialect operations. Structured diagnostics and recovery categories for failed dialect operations. Structured failures raised by math verification.

These errors are wrapped in pliron::result::Error. Use Diagnostic::from_error to recover the structured details.

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.

InvalidOperation

An operation’s attributes, types, or structure violate its contract.

Fields

operation: String

Operation name identifying the failed check.

location: String

Rendered source location, or a placeholder when no source is available.

reason: &'static str

Specific violated constraint; correct the IR before retrying.

Implementations

impl Diagnostic

pub fn from_error(error: &Error) -> Option<&Self>

Finds the first math diagnostic in an error and its source chain.

Traverses framework err payloads as well as standard error sources.

pub fn recovery_category(&self) -> RecoveryCategory

Classifies the action a caller should take before retrying.

Trait Implementations

impl Debug for Diagnostic

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

Formats the value using the given formatter.

impl Display for Diagnostic

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

Formats the value using the given formatter.

impl Error for Diagnostic

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<Diagnostic> for Error

fn from(diagnostic: Diagnostic) -> Self

Converts to this type from the input type.
