Represents any error thrown by the Environment

Variants

Return(ConValue)

Propagate a Return value

Break(ConValue)

Propagate a Break value

BadBreak(ConValue)

Break propagated across function bounds

Continue

Continue to the next iteration of a loop

StackUnderflow

Underflowed the stack

ScopeExit

Exited the last scope

TypeError

Type incompatibility

NotIterable

In clause of For loop didn’t yield a Range

NotIndexable

A value could not be indexed

OobIndex(usize, usize)

An array index went out of bounds

NotAssignable

An expression is not assignable

NotDefined(Sym)

A name was not defined in scope before being used

NotInitialized(Sym)

A name was defined but not initialized

NotCallable(ConValue)

A value was called, but is not callable

ArgNumber

A function was called with the wrong number of arguments

Fields

want: usize

got: usize

NullPointer

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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.
