[+] Show hidden undocumented items

type Err = SysctlError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>[−]

Parses a string s to return a value of this type.

impl IntoIterator for Ctl[+]

Ctl implements the IntoIterator trait to allow for easy iteration over nodes.

Example

extern crate sysctl;
use sysctl::Sysctl;

let kern = sysctl::Ctl::new("kern");
for ctl in kern {
    println!("{}", ctl.name().unwrap());
}

type Item = Result<Ctl, SysctlError>

The type of the elements being iterated over.

type IntoIter = CtlIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter[−]

Creates an iterator from a value.

fn eq(&self, other: &Ctl) -> bool[−]

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Ctl) -> bool[−]

This method tests for !=.

impl StructuralPartialEq for Ctl

impl Sysctl for Ctl[+]

[+] Show hidden undocumented items

fn new(name: &str) -> Result<Self, SysctlError>[−]

Construct a Ctl from the name.

fn name(&self) -> Result<String, SysctlError>[−]

Returns a result containing the sysctl name on success, or a SysctlError on failure.

fn value_type(&self) -> Result<CtlType, SysctlError>[−]

Returns a result containing the sysctl value type on success, or a Sysctl Error on failure.

fn description(&self) -> Result<String, SysctlError>[−]

Returns a result containing the sysctl description if success, or an Error on failure.

fn value(&self) -> Result<CtlValue, SysctlError>[−]

Returns a result containing the sysctl value on success, or a SysctlError on failure.

fn value_as<T>(&self) -> Result<Box<T>, SysctlError>[−]

A generic method that takes returns a result containing the sysctl value if success, or a SysctlError on failure.

fn value_string(&self) -> Result<String, SysctlError>[−]

Returns a result containing the sysctl value as String on success, or a SysctlError on failure.

fn set_value(&self, value: CtlValue) -> Result<CtlValue, SysctlError>[−]

Sets the value of a sysctl. Fetches and returns the new value if successful, or returns a SysctlError on failure. # Example ```ignore extern crate sysctl; extern crate libc; use sysctl::Sysctl;

fn set_value_string(&self, value: &str) -> Result<String, SysctlError>[−]

Sets the value of a sysctl with input as string. Fetches and returns the new value if successful, or returns a SysctlError on failure. # Example ```ignore extern crate sysctl; use sysctl::Sysctl;

fn flags(&self) -> Result<CtlFlags, SysctlError>[−]

Get the flags for a sysctl.

fn info(&self) -> Result<CtlInfo, SysctlError>[−]

Returns a Result containing the control metadata for a sysctl.
