Struct TagCounts 

#[non_exhaustive]
pub struct TagCounts {
    pub tag: u16,
    pub class: u8,
    pub name: &'static str,
    pub live_bytes: u64,
    pub live_blocks: u32,
    pub allocated_bytes: u64,
    pub peak_bytes: u64,
}

One memory tag’s counts in a CountingAlloc::with_tags (CountingAlloc::rows), in bytes asked for. Build it with TagCounts::new (ADR-0039).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

tag: u16

The tag (tags::tag).

class: u8

Its name’s class, as tags::tag was given it; tags::OTHER_CLASS for other and overflow.

name: &'static str

Its name: other for tag 0, overflow for tag 255.

live_bytes: u64

The bytes live under it.

live_blocks: u32

The blocks live under it.

allocated_bytes: u64

The bytes ever allocated under it: a realloc adds its new size (a machine word: on a 32-bit target it wraps past 4 GiB).

peak_bytes: u64

The most bytes live under it at once.
