Enum Error

pub enum Error {
    ToJsConversionError {
        from: &'static str,
        to: &'static str,
    },
    FromJsConversionError {
        from: &'static str,
        to: &'static str,
    },
    Timeout,
    RecursiveMutCallback,
    InvalidTimeout,
    ExternalError(Box<dyn StdError + 'static>),
    Value(Value),
}

An error originating from MiniV8 usage.

Variants

ToJsConversionError

A Rust value could not be converted to a JavaScript value.

Fields

from: &'static str

Name of the Rust type that could not be converted.

to: &'static str

Name of the JavaScript type that could not be created.

FromJsConversionError

A JavaScript value could not be converted to the expected Rust type.

Fields

from: &'static str

Name of the JavaScript type that could not be converted.

to: &'static str

Name of the Rust type that could not be created.

Timeout

An evaluation timeout occurred.

RecursiveMutCallback

A mutable callback has triggered JavaScript code that has called the same mutable callback again.

This is an error because a mutable callback can only be borrowed mutably once.

InvalidTimeout

An evaluation timeout was specified from within a Rust function embedded in V8.

ExternalError(Box<dyn StdError + 'static>)

A custom error that occurs during runtime.

This can be used for returning user-defined errors from callbacks.

Value(Value)

An exception that occurred within the JavaScript environment.

Implementations

impl Error

pub fn to_value(self, mv8: &MiniV8) -> Value

Normalizes an error into a JavaScript value.

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 description(&self) -> &'static str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

Returns the lower-level source of this error, if any.

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.
