Variants

CycleDetected

MissingRoot

MissingNode(NodeId)

TypeError

Fields

message: String

span: Option<Span>

file: Option<String>

PatchError

A patch application failure with its own stable code (E019): rename conflicts and invalid paths discovered at apply time. Missing remove/rename targets warn (W004) instead of failing.

Fields

message: String

span: Option<Span>

file: Option<String>

SecretLeak

Fields

file: Option<String>

ValidationFailed

Schema validation failures (C-031, spec/validation.md) and constraint failures (C-034, spec/annotations.md): every violation diagnostic, collected in deterministic order. Strict mode returns these instead of a value tree; resilient mode keeps them as ordinary diagnostics alongside the tree.

Fields

diagnostics: Vec<Diagnostic>

BudgetExceeded

Execution budget violations (C-037, spec/budgets.md): always fatal, in strict and resilient modes alike — budgets protect the process, not the document.

Fields

kind: BudgetKind

limit: u64

span: Option<Span>

file: Option<String>

Implementations

impl EvalError

pub fn code(&self) -> &'static str

Stable diagnostic code for this error class (see docs/diagnostics.md).

pub fn span(&self) -> Option<&Span>

Source span when the error can be attributed to a node position.

pub fn file(&self) -> Option<&str>

Source file when the error can be attributed to a node position (multi-file documents via includes, C-025).

Trait Implementations

impl Debug for EvalError

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

Formats the value using the given formatter.

impl Display for EvalError

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

Formats the value using the given formatter.

impl Error for EvalError

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.
