Struct HeapBucket 

pub struct HeapBucket {
    pub type_name: &'static str,
    pub count: usize,
    pub bytes_approx: usize,
}

One per-type row in HeapSnapshot::buckets.

Fields

type_name: &'static str

Lower-cased name of the ObjTag discriminant ("str", "table", "proto", …).

count: usize

Count of live objects with this tag.

bytes_approx: usize

Per-tag byte estimate. Uses core::mem::size_of of the payload struct as a lower bound — mirrors Heap::bytes’s “shells only” accounting; embedders that need exact bytes must instrument allocations themselves.
