Enum RError 

pub enum RError {
    Standard {
        kind: RErrorKind,
        message: String,
        source: Option<Arc<dyn Error + Send + Sync>>,
    },
    Condition {
        condition: RValue,
        kind: ConditionKind,
    },
}

R runtime error — wraps any module error with an R-facing category and preserves the full error chain via Arc<dyn Error>.

Construct via RError::new(), RError::from_source(), or From<T: Error> impls. Module errors (IoError, MathError, etc.) convert automatically via the blanket impl.

Variants

Standard

Standard error with kind, message, and optional source chain.

Fields

kind: RErrorKind

message: String

source: Option<Arc<dyn Error + Send + Sync>>

Condition

R condition signal — carries a condition object (list with class attribute). This is distinct from standard errors because it carries an RValue, not a std::error::Error.

Fields

condition: RValue

kind: ConditionKind

Implementations

impl RError

pub fn new(kind: RErrorKind, message: impl Into<String>) -> Self

Create an error with a kind and message (no source chain).

pub fn from_source( kind: RErrorKind, source: impl Error + Send + Sync + 'static, ) -> Self

Create an error that wraps a source error, using its Display as the message.

pub fn other(message: impl Into<String>) -> Self

Convenience: create an Other error with just a message.

pub fn interrupt() -> Self

Create an interrupt error (Ctrl+C during computation).

pub fn is_interrupt(&self) -> bool

Returns true if this error represents a user interrupt (Ctrl+C).

pub fn kind(&self) -> Option<RErrorKind>

Return the error kind (or None for Condition).

pub fn message(&self) -> String

Extract the error message string from any RError variant.

pub fn source(&self) -> Option<&(dyn Error + Send + Sync)>

Get the source error, if any.

Trait Implementations

impl Clone for RError

fn clone(&self) -> RError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RError

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

Formats the value using the given formatter.

impl Display for RError

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

Formats the value using the given formatter.

impl From<AssignmentError> for RError

fn from(e: AssignmentError) -> Self

Converts to this type from the input type.

impl From<DateTimeError> for RError

fn from(e: DateTimeError) -> Self

Converts to this type from the input type.

impl From<IndexingError> for RError

fn from(e: IndexingError) -> Self

Converts to this type from the input type.

impl From<IoError> for RError

fn from(e: IoError) -> Self

Converts to this type from the input type.

impl From<MathError> for RError

Available on crate feature linalg only.

fn from(e: MathError) -> Self

Converts to this type from the input type.

impl From<RError> for RFlow

fn from(e: RError) -> Self

Converts to this type from the input type.

impl From<RFlow> for RError

fn from(f: RFlow) -> Self

Convert back from RFlow to RError. Signals become Other errors (they shouldn’t normally reach builtin boundaries, but if they do we don’t lose information).

impl From<RandomError> for RError

fn from(e: RandomError) -> Self

Converts to this type from the input type.

impl From<StringError> for RError

fn from(e: StringError) -> Self

Converts to this type from the input type.

impl From<SystemError> for RError

fn from(e: SystemError) -> Self

Converts to this type from the input type.

impl From<TryFromIntError> for RError

fn from(e: TryFromIntError) -> Self

Converts to this type from the input type.
