}
Expand description

A structure representing control metadata

Fields§

§ctl_type: CtlType

The control type.

§fmt: String

A string which specifies the format of the OID in a symbolic way.

This format is used as a hint by sysctl(8) to apply proper data formatting for display purposes.

Formats defined in sysctl(9):

  • N node
  • A char *
  • I int
  • IK[n] temperature in Kelvin, multiplied by an optional single digit power of ten scaling factor: 1 (default) gives deciKelvin, 0 gives Kelvin, 3 gives milliKelvin
  • IU unsigned int
  • L long
  • LU unsigned long
  • Q quad_t
  • QU u_quad_t
  • S,TYPE struct TYPE structures
§flags: u32

Implementations§

source§

impl CtlInfo

source

pub fn is_temperature(&self) -> bool

Is this sysctl a temperature?

source§

impl CtlInfo

source

pub fn flags(&self) -> CtlFlags

Return the flags for this sysctl.

source

pub fn struct_type(&self) -> Option<String>

If the sysctl is a structure, return the structure type string.

Checks whether the format string starts with S, and returns the rest of the format string or None if the format String does not have a struct hint.

Trait Implementations§

impl Debug for CtlInfo

source§

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more
source§

impl PartialEq for CtlInfo

source§

fn eq(&self, other: &CtlInfo) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
