Enum EngineError 

pub enum EngineError {
    ParseError {
        source: String,
        message: String,
    },
    ComponentNotFound(String),
    RenderError(String),
    ActionNotFound(String),
    StateError(String),
    ExpressionError(String),
}

Structured error type for Hypen Engine operations.

SDK authors can pattern-match on variants to distinguish between different failure modes and provide appropriate error messages.

Variants

ParseError

Error parsing Hypen DSL source code.

source contains the input text (or a truncated prefix) that failed to parse. message contains the human-readable parse error.

Fields

source: String

message: String

ComponentNotFound(String)

A referenced component was not found in the registry.

Contains the component name that could not be resolved.

RenderError(String)

Error during rendering or reconciliation.

ActionNotFound(String)

No handler registered for the dispatched action.

Contains the action name that had no handler.

StateError(String)

Error related to state operations (invalid patch, deserialization failure).

ExpressionError(String)

Error evaluating an expression or template string.

Trait Implementations

impl Clone for EngineError

fn clone(&self) -> EngineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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<String> for EngineError

Convert from a String error (backward compatibility for internal code).

fn from(msg: String) -> Self

Converts to this type from the input type.

impl PartialEq for EngineError

fn eq(&self, other: &EngineError) -> 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.
