Enum OpcValue 

pub enum OpcValue {
    String(String),
    Int(i32),
    Float(f64),
    Bool(bool),
}

Typed value to write to an OPC DA tag.

Examples

use opc_da_client::OpcValue;

let v = OpcValue::Float(3.14);
assert_eq!(v, OpcValue::Float(3.14));

Variants

String(String)

String value (VT_BSTR) — server may coerce to target type.

Int(i32)

32-bit integer (VT_I4).

Float(f64)

64-bit float (VT_R8).

Bool(bool)

Boolean (VT_BOOL).

Trait Implementations

impl Clone for OpcValue

fn clone(&self) -> OpcValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpcValue

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

Formats the value using the given formatter.

impl PartialEq for OpcValue

fn eq(&self, other: &OpcValue) -> 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.
