tetsy-util-mem

Collection of memory related utilities.

WARNING

When tetsy-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 tetsy-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 or size_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This crate groups common dependency, a patched copy of unpublished malloc_size_of from servo project is copied and partially reexported.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.
