Process Control

This crate allows running a process with resource limits, such as a running time, and the option to terminate it automatically afterward. The latter is surprisingly difficult to achieve on Unix, since process identifiers can be arbitrarily reassigned when no longer used. Thus, it would be extremely easy to inadvertently terminate an unexpected process. This crate protects against that possibility.

Methods for setting limits are available on ChildExt, which is implemented for Child. They each return a builder of options to configure how the limit should be applied.

Warning: This crate should not be used for security. There are many ways that a process can bypass resource limits. The limits are only intended for simple restriction of harmless processes.

GitHub Build Status


Add the following lines to your "Cargo.toml" file:

process_control = "4.1"

See the documentation for available functionality and examples.

Rust version support

The minimum supported Rust toolchain version is currently Rust 1.74.0.

Minor version updates may increase this version requirement. However, the previous two Rust releases will always be supported. If the minimum Rust version must not be increased, use a tilde requirement to prevent updating this crate's minor version:

process_control = "~4.1"
