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.
