}Expand description
Approximations of stack and heap size for both internal and external types.
Motly used for statistics and triggering events such as garbage collection.
Required Methods§
sourcefn heap_size_bytes(&self) -> u64
fn heap_size_bytes(&self) -> u64
Returns the total size of self on the heap, in bytes.
Provided Methods§
sourcefn total_size_bytes(&self) -> u64
fn total_size_bytes(&self) -> u64
Returns the total size of self in bytes, accounting for both stack and heap space.
sourcefn stack_size_bytes(&self) -> u64
fn stack_size_bytes(&self) -> u64
Returns the total size of self on the stack, in bytes.
Defaults to std::mem::size_of_val(self).
Object Safety§
This trait is not object safe.
