Struct StackTrace

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

Representation of a JavaScript stack trace. The information collected is a snapshot of the execution stack and the information remains valid after execution continues.

Implementations

impl StackTrace

pub fn get_frame_count(&self) -> usize

Returns the number of StackFrames.

pub fn get_frame<'s>( &self, scope: &mut HandleScope<'s>, index: usize, ) -> Option<Local<'s, StackFrame>>

Returns a StackFrame at a particular index.

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 StackTrace

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

Formats the value using the given formatter.

impl Hash for StackTrace

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 StackTrace

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<StackTrace> for Data

fn eq(&self, other: &StackTrace) -> 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 StackTrace

fn eq(&self, other: &StackTrace) -> 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 StackTrace

type Target = Data

The resulting type after dereferencing.

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

Dereferences the value.
