Trait MallocSizeOf 

pub trait MallocSizeOf {
    // Required method
    fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize;
}

Trait for measuring the “deep” heap usage of a data structure. This is the most commonly-used of the traits.

Required Methods

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

impl<T: MallocSizeOf> MallocSizeOf for Mutex<T>

If a mutex is stored directly as a member of a data type that is being measured, it is the unique owner of its contents and deserves to be measured.

If a mutex is stored inside of an Arc value as a member of a data type that is being measured, the Arc will not be automatically measured so there is no risk of overcounting the mutex’s contents.
