Implementations

impl FunctionCode

pub const fn new(value: u8) -> Self

Create a new FunctionCode with value.

pub const fn value(self) -> u8

Get the u8 value of the current FunctionCode.

Panics

Panics on Disconnect which has no corresponding Modbus function code.

Trait Implementations

impl Clone for FunctionCode

fn clone(&self) -> FunctionCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionCode

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

Formats the value using the given formatter.

impl Display for FunctionCode

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

Formats the value using the given formatter.

impl PartialEq for FunctionCode

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

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

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.
