Trait MemoryReport 

pub trait MemoryReport: Sized {
    const ALLOC: bool = false;
    const CHILD: bool = false;

    // Provided methods
    fn direct() -> usize { ... }
    fn indirect(&self) -> usize { ... }
    fn children(&self) -> usize { ... }
}

Provided Associated Constants

const ALLOC: bool = false

A constant that indicates whether this object allocates memory other than the innate memory.

const CHILD: bool = false

A constant that indicates whether this object has children.

Provided Methods

fn direct() -> usize

Reports the memory innate to the struct. This is equivalent to core::mem::size_of::<Self>().

fn indirect(&self) -> usize

Reports the memory directly allocated by this struct. For example, Vec returns its capacity times the size of the structs.

fn children(&self) -> usize

Reports the indirect and children memory of the children of the struct, if there are any. This returns non zero only if the children of the struct allocate memory. For example Vec<Vec<T>> would return a non zero value but a Vec<usize> would return 0.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
