Methods

impl Nice

pub fn set_autogroup_for_current_process(
    self,
    proc_path: &ProcPath
) -> Result<(), Error>

Set the autogroup for the current process.

pub fn set_autogroup_for_current_process_if_desired(
    only_set_if_is_some: Option<Self>,
    proc_path: &ProcPath
) -> Result<(), Error>

Set the autogroup for the current process.

pub fn set_current_process_group_priority(self) -> Result<(), ()>

Returns an Err() if the user did not have permission to adjust the priority (eg was not privileged or had the capability CAP_SYS_NICE).

pub fn set_current_real_effective_user_priority(self) -> Result<(), ()>

Returns an Err() if the user did not have permission to adjust the priority (eg was not privileged or had the capability CAP_SYS_NICE).
