Expand description
This crate provides to an interface into the linux procfs filesystem, usually mounted at
/proc.
This is a pseudo-filesystem which is available on most every linux system and provides an interface to kernel data structures.
§procfs-core
The procfs-core crate is a fully platform-independent crate that contains most of the data-structures and
parsing code. Most people should first look at the procfs crate instead.
Re-exports§
pub use sys::kernel::Version as KernelVersion;
Modules§
- keyring
- Functions related to the in-kernel key management and retention facility
- net
- Information about the networking layer.
- prelude
- Extension traits useful for importing wholesale.
- process
- Functions and structs related to process information
- sys
- Sysctl is a means of configuring certain aspects of the kernel at run-time,
and the
/proc/sys/directory is there so that you don’t even need special tools to do it!
