Struct Message

#[repr(C)]
pub struct Message(/* private fields */);

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

Methods from Deref<Target = Data>

pub fn get_hash(&self) -> int

Returns the V8 hash value for this value. The current implementation uses a hidden property to store the identity hash on some object types.

The return value will never be 0. Also, it is not guaranteed to be unique.

pub fn is_value(&self) -> bool

Returns true if this data is a Value.

pub fn is_module(&self) -> bool

Returns true if this data is a Module.

pub fn is_private(&self) -> bool

Returns true if this data is a Private.

pub fn is_object_template(&self) -> bool

Returns true if this data is an ObjectTemplate

pub fn is_function_template(&self) -> bool

Returns true if this data is a FunctionTemplate.

Trait Implementations

impl Debug for Message

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

Formats the value using the given formatter.

impl Hash for Message

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'s> PartialEq<Data> for Message

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'s> PartialEq<Message> for Data

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'s> PartialEq for Message

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Deref for Message

type Target = Data

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
