Struct v8::Message

#[repr(C)]
pub struct Message(_);

An error message.

Implementations

impl Message

pub fn get<'s>(&self, scope: &mut HandleScope<'s>) -> Local<'s, String>

pub fn get_stack_trace<'s>( &self, scope: &mut HandleScope<'s> ) -> Option<Local<'s, StackTrace>>

Exception stack trace. By default stack traces are not captured for uncaught exceptions. SetCaptureStackTraceForUncaughtExceptions allows to change this option.

pub fn get_source_line<'s>( &self, scope: &mut HandleScope<'s> ) -> Option<Local<'s, String>>

pub fn get_script_resource_name<'s>( &self, scope: &mut HandleScope<'s> ) -> Option<Local<'s, Value>>

Returns the resource name for the script from where the function causing the error originates.

pub fn get_line_number(&self, scope: &mut HandleScope<'_>) -> Option<usize>

Returns the number, 1-based, of the line where the error occurred.

pub fn get_start_position(&self) -> int

Returns the index within the script of the first character where the error occurred.

pub fn get_end_position(&self) -> int

Returns the index within the script of the last character where the error occurred.

pub fn get_wasm_function_index(&self) -> int

Returns the Wasm function index where the error occurred. Returns -1 if message is not from a Wasm script.

pub fn error_level(&self) -> int

Returns the error level of the message.

pub fn get_start_column(&self) -> usize

Returns the index within the line of the first character where the error occurred.

pub fn get_end_column(&self) -> usize

Returns the index within the line of the last character where the error occurred.

pub fn is_shared_cross_origin(&self) -> bool

Passes on the value set by the embedder when it fed the script from which this Message was generated to V8.

pub fn is_opaque(&self) -> bool

Trait Implementations

impl Debug for Message

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

Formats the value using the given formatter.

impl<'s> PartialEq<Message> for Message

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
