An error that may occur while creating a type from a Ruby Value.

Variants

Cycle

An already visited node was visited.

Fields

handle: ValueHandle

The already-visited node.

InvalidValueHandle

A given ValueHandle was invalid.

Fields

handle: ValueHandle

The invalid handle

UnexpectedValueKind

An unexpected value kind was encountered.

Fields

kind: ValueKind

The unexpected value kind

trace: Vec<ValueHandle>

The current path of value handles

UnexpectedObjectName

An object name was unexpected.

Fields

name: Vec<u8>

The object name.

This may or may not be UTF-8.

UnexpectedUserDefinedName

A user defined value name was unexpected.

Fields

name: Vec<u8>

The user defined name.

This may or may not be UTF-8.

DuplicateInstanceVariable

An instance variable was duplicated

Fields

name: Vec<u8>

The instance variable name.

This may or may not be UTF-8.

UnknownInstanceVariable

An unknown instance variable was encountered.

Fields

name: Vec<u8>

The instance variable name.

This may or may not be UTF-8.

MissingInstanceVariable

Missing an instance variable with the given name.

Fields

name: Vec<u8>

The instance variable name.

This may or may not be UTF-8.

DuplicateHashKey

A hash key was provided twice.

Fields

key: ValueHandle

The key that was provided twice.

This does not need to be a symbol.

Other

Another user-provided kind of error occured.

Fields

error: Box<dyn Error + Send + Sync + 'static>

Implementations

impl FromValueError

pub fn new_other<E>(error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync + 'static>>,

Shorthand for creating a new Other error variant.

Trait Implementations

impl Debug for FromValueError

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

Formats the value using the given formatter.

impl Display for FromValueError

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

Formats the value using the given formatter.

impl Error for FromValueError

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
