Trait MallocShallowSizeOf 

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

Trait for measuring the “shallow” heap usage of a container.

Required Methods

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

Measure the heap usage of immediate heap-allocated descendant structures, but not the space taken up by the value itself. Anything beyond the immediate descendants must be measured separately, using iteration.

Dyn Compatibility

This trait is dyn compatible.

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