Struct rusty_v8::StackFrame

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

A single JavaScript stack frame.

Implementations

impl StackFrame

pub fn get_line_number(&self) -> usize

Returns the number, 1-based, of the line for the associate function call. This method will return Message::kNoLineNumberInfo if it is unable to retrieve the line number, or if kLineNumber was not passed as an option when capturing the StackTrace.

pub fn get_column(&self) -> usize

Returns the 1-based column offset on the line for the associated function call. This method will return Message::kNoColumnInfo if it is unable to retrieve the column number, or if kColumnOffset was not passed as an option when capturing the StackTrace.

pub fn get_script_id(&self) -> usize

Returns the id of the script for the function for this StackFrame. This method will return Message::kNoScriptIdInfo if it is unable to retrieve the script id, or if kScriptId was not passed as an option when capturing the StackTrace.

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

Returns the name of the resource that contains the script for the function for this StackFrame.

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

Returns the name of the resource that contains the script for the function for this StackFrame or sourceURL value if the script name is undefined and its source ends with //# sourceURL=... string or deprecated //@ sourceURL=... string.

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

Returns the name of the function associated with this stack frame.

pub fn is_eval(&self) -> bool

Returns whether or not the associated function is compiled via a call to eval().

pub fn is_constructor(&self) -> bool

Returns whether or not the associated function is called as a constructor via "new".

pub fn is_wasm(&self) -> bool

Returns whether or not the associated functions is defined in wasm.

pub fn is_user_javascript(&self) -> bool

Returns whether or not the associated function is defined by the user.

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.

Trait Implementations

impl Deref for StackFrame

type Target = Data

The resulting type after dereferencing.

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

Dereferences the value.

impl Eq for StackFrame

impl Hash for StackFrame

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, 

Feeds a slice of this type into the given [Hasher].

impl<'s> PartialEq<Data> for StackFrame

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<'s> PartialEq<StackFrame> for Data

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<'s> PartialEq<StackFrame> for StackFrame

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
