Struct parity_util_mem::MallocSizeOfOps [−][src]
Operations used when measuring heap usage of data structures.
Implementations
impl MallocSizeOfOps[src]
pub fn new(
size_of: unsafe extern "C" fn(ptr: *const c_void) -> usize,
malloc_enclosing_size_of: Option<unsafe extern "C" fn(ptr: *const c_void) -> usize>,
have_seen_ptr: Option<Box<dyn FnMut(*const c_void) -> bool>>
) -> Self[src]
size_of: unsafe extern "C" fn(ptr: *const c_void) -> usize,
malloc_enclosing_size_of: Option<unsafe extern "C" fn(ptr: *const c_void) -> usize>,
have_seen_ptr: Option<Box<dyn FnMut(*const c_void) -> bool>>
) -> Self
pub unsafe fn malloc_size_of<T: ?Sized>(&self, ptr: *const T) -> usize[src]
Call size_of_op on ptr, first checking that the allocation isn’t
empty, because some types (such as Vec) utilize empty allocations.
pub fn has_malloc_enclosing_size_of(&self) -> bool[src]
Is an enclosing_size_of_op available?
pub unsafe fn malloc_enclosing_size_of<T>(&self, ptr: *const T) -> usize[src]
Call enclosing_size_of_op, which must be available, on ptr, which
must not be empty.
pub fn have_seen_ptr<T>(&mut self, ptr: *const T) -> bool[src]
Call have_seen_ptr_op on ptr.
