source · [−]#[repr(C)]pub struct StackFrame(_);
Expand description
A single JavaScript stack frame.
Implementations
sourceimpl StackFrame
impl StackFrame
sourcepub fn get_line_number(&self) -> usize
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.
sourcepub fn get_column(&self) -> usize
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.
sourcepub fn get_script_id(&self) -> usize
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.
sourcepub fn get_script_name<'s>(
&self,
scope: &mut HandleScope<'s>
) -> Option<Local<'s, String>>
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.
sourcepub fn get_script_name_or_source_url<'s>(
&self,
scope: &mut HandleScope<'s>
) -> Option<Local<'s, String>>
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.
sourcepub fn get_function_name<'s>(
&self,
scope: &mut HandleScope<'s>
) -> Option<Local<'s, 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.
sourcepub fn is_eval(&self) -> bool
pub fn is_eval(&self) -> bool
Returns whether or not the associated function is compiled via a call to eval().
sourcepub fn is_constructor(&self) -> bool
pub fn is_constructor(&self) -> bool
Returns whether or not the associated function is called as a constructor via “new”.
sourcepub fn is_wasm(&self) -> bool
pub fn is_wasm(&self) -> bool
Returns whether or not the associated functions is defined in wasm.
sourcepub fn is_user_javascript(&self) -> bool
pub fn is_user_javascript(&self) -> bool
Returns whether or not the associated function is defined by the user.
Methods from Deref<Target = Data>
sourcepub fn get_hash(&self) -> int
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.
sourcepub fn is_private(&self) -> bool
pub fn is_private(&self) -> bool
Returns true if this data is a Private
.
sourcepub fn is_object_template(&self) -> bool
pub fn is_object_template(&self) -> bool
Returns true if this data is an ObjectTemplate
sourcepub fn is_function_template(&self) -> bool
pub fn is_function_template(&self) -> bool
Returns true if this data is a FunctionTemplate.
