Struct deno_core::error::JsError

pub struct JsError {
    pub message: String,
    pub source_line: Option<String>,
    pub script_resource_name: Option<String>,
    pub line_number: Option<i64>,
    pub start_column: Option<i64>,
    pub end_column: Option<i64>,
    pub frames: Vec<JsStackFrame>,
    pub stack: Option<String>,
}

A JsError represents an exception coming from V8, with stack frames and line numbers. The deno_cli crate defines another JsError type, which wraps the one defined here, that adds source map support and colorful formatting.

pub fn from_v8_exception(
    scope: &mut HandleScope<'_>,
    exception: Local<'_, Value>
) -> Self

Trait Implementations

impl Clone for JsError

fn clone(&self) -> JsError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JsError

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

Formats the value using the given formatter.

impl Display for JsError

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

Formats the value using the given formatter.

impl Error for JsError

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

impl PartialEq<JsError> for JsError

fn eq(&self, other: &JsError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &JsError) -> bool

This method tests for !=.
