Crate dlmalloc

A Rust port of the dlmalloc allocator.

The dlmalloc allocator is described at https://gee.cs.oswego.edu/dl/html/malloc.html and this Rust crate is a straight port of the C code for the allocator into Rust. The implementation is wrapped up in a Dlmalloc type and has support for Linux, OSX, and Wasm currently.

The primary purpose of this crate is that it serves as the default memory allocator for the wasm32-unknown-unknown target in the standard library. Support for other platforms is largely untested and unused, but is used when testing this crate.

Structs

• Dlmalloc
  An allocator instance
• GlobalDlmalloc
  An instance of a “global allocator” backed by Dlmalloc

Traits

• Allocator
  In order for this crate to efficiently manage memory, it needs a way to communicate with the underlying platform. This Allocator trait provides an interface for this communication.

Functions

• enable_alloc_after_fork^⚠
  allows the allocator to remain unsable in the child process, after a call to fork(2)
