Struct v8::SharedPtr

#[repr(C)]
pub struct SharedPtr<T: Shared>(_);

Wrapper around a C++ shared_ptr. A shared_ptr may be be null.

Implementations

impl<T: Shared> SharedPtr<T>

pub fn assert_use_count_eq(&self, expected: usize)

Asserts that the number of references to the shared inner value is equal to the expected count.

This function relies on the C++ method std::shared_ptr::use_count(), which usually performs a relaxed load. This function will repeatedly call use_count() until it returns the expected value, for up to one second. Therefore it should probably not be used in performance critical code.

pub fn is_null(&self) -> bool

pub fn take(&mut self) -> Option<SharedRef<T>>

pub fn unwrap(self) -> SharedRef<T>
