Struct janetrs::function::CallError

pub struct CallError<'data> { /* fields omitted */ }

Error type that happens when calling a JanetFunction on the Rust side.

Implementations

impl<'data> CallError<'data>

pub const fn kind(&self) -> CallErrorKind

Returns the kind of the error.

pub const fn value(&self) -> Janet

Returns the error value.

pub const fn signal(&self) -> JanetSignal

Returns the JanetSignal that caused the error.

pub const fn fiber(&self) -> Option<&JanetFiber<'_>>

Get a reference to the fiber that the error happened if it exists.

pub fn fiber_mut(&mut self) -> Option<&mut JanetFiber<'data>>

Get a exclusive reference to the fiber that the error happened if it exists.

pub const fn take_fiber(self) -> Option<JanetFiber<'data>>

Consume the error and return the fiber that the error happened if it exists.

pub fn stacktrace<W: Write + ?Sized>(&mut self, output: &mut W) -> Result<()>

Display the stacktrace in the given output

Trait Implementations

impl<'data> Debug for CallError<'data>

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

Formats the value using the given formatter.

impl Display for CallError<'_>

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

Formats the value using the given formatter.

impl Error for CallError<'_>

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
