Expand description

Resource limits for the memory subsystem.

Fields§

§kernel_memory_limit: Option<i64>

How much memory (in bytes) can the kernel consume.

§memory_hard_limit: Option<i64>

Upper limit of memory usage of the control group’s tasks.

§memory_soft_limit: Option<i64>

How much memory the tasks in the control group can use when the system is under memory pressure.

§kernel_tcp_memory_limit: Option<i64>

How much of the kernel’s memory (in bytes) can be used for TCP-related buffers.

§memory_swap_limit: Option<i64>

How much memory and swap together can the tasks in the control group use.

§swappiness: Option<u64>

Controls the tendency of the kernel to swap out parts of the address space of the tasks to disk. Lower value implies less likely.

Note, however, that a value of zero does not mean the process is never swapped out. Use the traditional mlock(2) system call for that purpose.

§attrs: HashMap<String, String>

Customized key-value attributes

§Usage:

let resource = &mut cgroups_rs::fs::Resources::default();
resource.memory.attrs.insert("memory.numa_balancing".to_string(), "true".to_string());
// apply here
