Struct sysctl::CtlInfo

pub struct CtlInfo {
    pub ctl_type: CtlType,
    pub fmt: String,
    pub flags: u32,
}

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

impl CtlInfo

pub fn flags(&self) -> CtlFlags

Return the flags for this sysctl.

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

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

Formats the value using the given formatter.

impl PartialEq<CtlInfo> for CtlInfo

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

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

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

This method tests for !=.
