Struct v8::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 current_stack_trace<'s>( scope: &mut HandleScope<'s>, frame_limit: usize ) -> Option<Local<'s, StackTrace>>

Grab a snapshot of the current JavaScript execution stack.

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

Returns the first valid script name or source URL starting at the top of the JS stack. The returned string is either an empty handle if no script name/url was found or a non-zero-length string.

This method is equivalent to calling StackTrace::CurrentStackTrace and walking the resulting frames from the beginning until a non-empty script name/url is found. The difference is that this method won’t allocate a stack trace.

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.

Trait Implementations

impl Debug for StackTrace

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

Formats the value using the given formatter.

impl<'s> PartialEq for StackTrace

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