Variants

Allocation

Could not allocate memory This is generally only triggered when out of memory.

InvalidString(NulError)

Found a string with a internal null byte while converting to C string.

Utf8(Utf8Error)

String from rquickjs was not UTF-8

Unknown

An error from quickjs which i do not know the specifics about yet. Should eventually be removed as development progresses.

Exception

An exception raised by quickjs itself.

Methods

impl Error

pub fn is_exception(&self) -> bool

Returns wheter the error is a quickjs generated exception.

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, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for Error

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

impl From<Error> for Error

fn from(e: Error) -> Error

Performs the conversion.

impl From<NulError> for Error

fn from(e: NulError) -> Error

Performs the conversion.

impl From<Utf8Error> for Error

fn from(e: Utf8Error) -> Error

Performs the conversion.
