Struct ProcStatus

pub struct ProcStatus { /* private fields */ }

A snapshot of the status of a process

It’s stored in a string to ensure consistency and can be kept around and compared.

Implementations

impl ProcStatus

pub fn read() -> Result<Self, ProcStatusError>

read the proc status info of the current process.

It’s the same than ProcStatus::read(ProcRef::ProcSelf)

pub fn read_for(proc_ref: ProcRef) -> Result<Self, ProcStatusError>

read the proc status info of a process.

pub fn entries(&self) -> ProcEntries<'_>

return an iterator over all key:value entries

pub fn entry(&self, key: &str) -> Result<ProcEntry<'_>, ProcStatusError>

find an entry by name

pub fn value(&self, key: &str) -> Result<&str, ProcStatusError>

return the value of an entry found by key

Example:

println!(
    "current process name: {:?}",
    proc_status::ProcStatus::read().unwrap().value("Name").unwrap(),
);

Be careful that the values written as “xxx kB” are in KiB, not kB, and are written this way for compatibility.

pub fn value_KiB(&self, key: &str) -> Result<usize, ProcStatusError>

return the value of a memory related entry in KiB

pub fn mem_usage(&self) -> Result<MemUsage, ProcStatusError>

return the current and peak ram usage of the process
