Struct NtEnum 

pub struct NtEnum {
    pub index: i32,
    pub choices: Vec<String>,
    pub alarm: NtAlarm,
    pub time_stamp: NtTimeStamp,
}

NTEnum normative type — represents an enumerated PV value.

The index selects one of the choices strings. The wire layout matches the C++ epics:nt/NTEnum:1.0 structure:

structure "epics:nt/NTEnum:1.0"
  enum_t value
    int index
    string[] choices
  alarm_t alarm
  time_t timeStamp

Fields

index: i32

choices: Vec<String>

alarm: NtAlarm

time_stamp: NtTimeStamp

Implementations

impl NtEnum

pub fn new(index: i32, choices: Vec<String>) -> NtEnum

pub fn selected(&self) -> Option<&str>

Returns the currently selected choice string, or None if the index is out of range.

Trait Implementations

impl Clone for NtEnum

fn clone(&self) -> NtEnum

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NtEnum

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

Formats the value using the given formatter.

impl PartialEq for NtEnum

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

Tests for self and other values to be equal, and is used by ==.

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

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