#[repr(C)]pub struct SharedRef<T: Shared>(_);
Expand description
Wrapper around a C++ shared_ptr. The shared_ptr is assumed to contain a value and may not be null.
Implementations
sourceimpl<T: Shared> SharedRef<T>
impl<T: Shared> SharedRef<T>
sourcepub fn assert_use_count_eq(&self, expected: usize)
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.
