Trait loupe::MemoryUsage

pub trait MemoryUsage {
    fn size_of_val(&self, tracker: &mut dyn MemoryUsageTracker) -> usize;
}

Traverse a value and collect its memory usage.

Required methods

fn size_of_val(&self, tracker: &mut dyn MemoryUsageTracker) -> usize

Returns the size of the referenced value in bytes.

Recursively visits the value and any children returning the sum of their sizes. The size always includes any tail padding if applicable.
