parity-util-mem
Collection of memory related utilities.
WARNING
When parity-util-mem
is used as a dependency with any of the global allocator features enabled,
it must be the sole place where a global allocator is defined.
The only exception to this rule is when used in a no_std
context or when the estimate-heapsize
feature is used.
Because of that, it must be present in the dependency tree with a single version.
Starting from version 0.6.1, having duplicate versions of parity-util-mem
will lead
to a compile-time error. It still will be possible to have 0.5 and 0.6.1 versions in the same binary though.
Unless heeded you risk UB; see discussion in issue 364.
Features
- estimate-heapsize : Do not use allocator, but
size_of
orsize_of_val
.
Others features define global allocator, see src/alloc.rs
.
Dependency
This crate groups common dependency, a patched copy of unpublished malloc_size_of
from servo project is copied and partially reexported.
Malloc_size_of
code is used internally as a module with a few modification to be able to implement type locally.
For existing code using deprecated HeapsizeOf
crate, calls to heapsize_of_children
should be replace by calls to size_of
.
