Crate parity_util_mem

Crate for parity memory management related utilities. It includes global allocator choice, heap measurement and memory erasure.

Re-exports

pub use allocators::MallocSizeOfExt;

Modules

allocators

default allocator management Features are:

ethereum_impls

Implementation of MallocSize for common ethereum types: fixed hashes and uints.

primitives_impls

Implementation of MallocSize primitive types.

sizeof

Estimation for heapsize calculation. Usable to replace call to allocator method (for some allocators or simply because we just need a deterministic cunsumption measurement).

Macros

malloc_size_of_is_0

Implement notion of 0 allocation size for some type(s).

Structs

MallocSizeOfOps

Operations used when measuring heap usage of data structures.

MemoryAllocationSnapshot

Snapshot of collected memory metrics.

MemoryAllocationTracker

Accessor to the allocator internals.

MemoryStatsError

An error related to the memory stats gathering.

Traits

MallocShallowSizeOf

Trait for measuring the “shallow” heap usage of a container.

MallocSizeOf

Trait for measuring the “deep” heap usage of a data structure. This is the most commonly-used of the traits.

Functions

malloc_size

Heap size of structure.
