Enum PortState

pub enum PortState {
    Close,
    Open,
}

Represents the state of a single digital I/O port (e.g., relay).

Variants

Close

The port is inactive/relay OFF.

Open

The port is active/relay ON.

Implementations

impl PortState

pub fn decode_from_holding_registers(word: Word) -> Self

Decodes a PortState from a single Modbus holding register value (Word).

Arguments

• word: The Word (u16) value read from the Modbus register for this port.

Returns

The corresponding PortState.

Example

assert_eq!(PortState::decode_from_holding_registers(0x0000), PortState::Close);
assert_eq!(PortState::decode_from_holding_registers(0x0001), PortState::Open);
assert_eq!(PortState::decode_from_holding_registers(0xFFFF), PortState::Open);

Trait Implementations

impl Clone for PortState

fn clone(&self) -> PortState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PortState

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

Formats the value using the given formatter.

impl Display for PortState

Provides a human-readable string representation (“close” or “open”).

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

Formats the value using the given formatter.

impl Hash for PortState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PortState

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

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

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

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