Trait ByteSizeOf 

pub trait ByteSizeOf {
    // Required method
    fn allocated_bytes(&self) -> usize;

    // Provided method
    fn size_of(&self) -> usize { ... }
}

Required Methods

fn allocated_bytes(&self) -> usize

Returns the allocated bytes of this type

This function returns the total number of bytes that have been allocated interior to this type instance. It does not include any bytes that are captured by std::mem::size_of except for any bytes that are interior to this type. For instance, BTreeMap<String, Vec<u8>> would count all bytes for String and Vec<u8> instances but not the exterior bytes for BTreeMap.

Provided Methods

fn size_of(&self) -> usize

Returns the in-memory size of this type

This function returns the total number of bytes that std::mem::size_of does in addition to any interior allocated bytes. Its default implementation is std::mem::size_of + ByteSizeOf::allocated_bytes.
