Enum Error 

pub enum Error {
    CallError(CallError),
    CompilerError(CompilerError),
    IoError(Error),
    RuntimeError(LineCol, String),
    Break,
}

Error types for callable execution.

Variants

CallError(CallError)

Fails due to a callable-specific execution error.

CompilerError(CompilerError)

Fails due to a program compilation error.

IoError(Error)

Fails due to an I/O error in the underlying runtime.

RuntimeError(LineCol, String)

Fails due to a runtime error at a specific source location.

Break

Aborts execution due to an external break signal.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<CallError> for Error

fn from(source: CallError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: CompilerError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
