Crate pmem [−] [src]

FFI bindings to libpmem

Rust bindings for the NVM Library http://pmem.io

The pmem library provides low level persistent memory support. Developers wishing to roll their own persistent memory algorithms will find this library useful, but most developers will likely use pmem-obj and let that library call pmem for them.

The interfaces in pmem are non-transactional. Crates like pmem-obj provide transactional interfaces by building on these pmem functions.

This is not an official port of the NVM Library.

The official libpmem documentation can be found at: http://pmem.io/nvml/libpmem/

nodrain	The functions in this section provide optimized copying to persistent memory without draining
pmap	Persistent memory maps
ptr	The functions in this section provide optimized copying to persistent memory

Functions

check_version	Checks the version of the libpmem library
drain	Waits for any pmem stores to drain from HW buffers
errormsg	Description of the last error
flush	Flushes the processor caches
has_hw_drain	Wether or not the machine supports an explicit hardware drain instruction for persistent memory.
is_pmem	Checks if an entire object consists of persistent memory If `true` then it is safe to use `persist(1)` and other related functions to make changes durable for that memory range.
msync	Forces any changes in an object to be stored durably.
msync_unsized
persist	Force an object to be stored durably in persistent memory.
