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 associated 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.

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 StackFrame

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

Formats the value using the given formatter.

impl Deref for StackFrame

type Target = Data

The resulting type after dereferencing.

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

Dereferences the value.

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 ==.

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 ==.

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

This method tests for !=.

impl<'s> PartialEq<StackFrame> for StackFrame

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