Struct FunctionCallbackArguments 

pub struct FunctionCallbackArguments<'s>(/* private fields */);

Implementations

impl<'s> FunctionCallbackArguments<'s>

pub fn from_function_callback_info(info: &'s FunctionCallbackInfo) -> Self

pub unsafe fn get_isolate(&mut self) -> &mut Isolate

SAFETY: caller must guarantee that no other references to the isolate are accessible. Specifically, if an open CallbackScope or HandleScope exists in the current function, FunctionCallbackArguments::get_isolate() should not be called.

pub fn new_target(&self) -> Local<'s, Value>

For construct calls, this returns the “new.target” value.

pub fn is_construct_call(&self) -> bool

Returns true if this is a construct call, i.e., if the function was called with the new operator.

pub fn this(&self) -> Local<'s, Object>

Returns the receiver. This corresponds to the “this” value.

pub fn data(&self) -> Local<'s, Value>

Returns the data argument specified when creating the callback.

pub fn length(&self) -> int

The number of available arguments.

pub fn get(&self, i: int) -> Local<'s, Value>

Accessor for the available arguments. Returns undefined if the index is out of bounds.

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

Formats the value using the given formatter.
