Fields

objects: ArenaReport

shapes: ArenaReport

strings: ArenaReport

symbols: ArenaReport

bigints: ArenaReport

cells: ArenaReport

functions: ArenaReport

bytecode: ArenaReport

internals: ArenaReport

values: ValueHeapReport

rope_bytes: usize

Bytes of flattened ropes (the strings arena counts a rope as empty).

atoms: usize

Interned strings.

pinned_atoms: usize

Atoms that live as long as the heap.

code: CodeReport

register_capacity: usize

Registers the register file has room for.

register_high_water: usize

Registers made addressable so far: the file never shrinks, so this is its high-water mark.

ic_entries: usize

Inline-cache entries, held or free.

ic_free: usize

Entries no unit holds, reused by the next units published.

gc: GcStats

allocated_since_gc: usize

Nominal bytes allocated since the last collection, and the count at which the next one runs.

threshold: usize

budget: usize

The reserved-bytes budget the last collection set.

table_bytes: usize

Bytes of the tables beside the arenas: the ropes’ halves, the atom table and the inline caches.

cap: usize

The heap cap in bytes; usize::MAX for none.

Implementations

impl MemoryReport

pub fn arenas(&self) -> [(&'static str, &ArenaReport); 9]

The arenas by name, in report order.

pub fn reserved_bytes(&self) -> usize

Bytes reserved on the heap: what the cap compares against.
