Base cpufreq functionality for reading and writing on cpu variables

Required Associated Constants

const CPUFREQ_PATH: &'static str

Provided Methods

fn read_file(fname: &str) -> Result<String, Error>

Read file on CPUFREQ_PATH

Panics

Panics if the content of the file is not utf8 encoded

fn write_file(fname: &str, data: &str) -> Result<(), Error>

Write to file on CPUFREQ_PATH

fn get_ranges(fname: &str) -> Result<Vec<usize>, Error>

Read and parse cpufreq ranges, example: 0,4,6-12,18 -> [0,4,6,7,8,9,10,12,18]

Panics

Panics if values cannot be parsed to usize

fn get_variable<T>(id: usize, var: &str) -> Result<T, Box<dyn Error>>

where T: FromStr, T::Err: Error + 'static,

Read a specific variable and parse to T

fn set_variable(id: usize, var: &str, data: &str) -> Result<(), Error>

Sets a specific variable

fn get_variable_all<T>(var: &str) -> Result<HashMap<usize, T>, Box<dyn Error>>

where T: FromStr, T::Err: Error + 'static,

Get variables for all online cpus

fn set_variable_all(var: &str, data: &str) -> Result<(), Error>

Set variables for all online cpus

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
