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_thread_priority(self) -> Result<(), ()>

This is a Linux-only thing.

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_process_priority(self) -> Result<(), ()>

This replaces the use of the legacy nice() function.

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).

On Linux, actually sets the priority for only the current thread.

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).
