Trait bevy_datasize::DataSizeEstimator

pub trait DataSizeEstimator<T: ?Sized> {
    const IS_DYNAMIC: bool;

    fn estimate_heap_size(&self, value: &T) -> usize;
}

Indicates that a type can estimate the heap usage of values of type T.

This trait exists in order to work around the fact that this crate cannot add impls of DataSize to types from the Bevy crate(s).

Associated Constants

const IS_DYNAMIC: bool

If true, the type T has a heap size that can vary at runtime, depending on the actual value.

Required methods

fn estimate_heap_size(&self, value: &T) -> usize

Estimates the size of heap memory taken up by the given value.

Does not include data on the stack, which is usually determined using std::mem::size_of.
