Defines the set of operations supported by the PK Command protocol.

Variants

SendVariable

To set a variable’s value on the device.

5-character name: SENDV

RequireVariable

To get a variable’s value from the device.

5-character name: REQUV

Invoke

To invoke a method on the device.

5-character name: INVOK

GetVersion

To get the version of the PK Command processor on the device.

5-character name: PKVER

Start

To indicate the start of a transaction chain.

This is used internally by the poll method to manage transaction stages and usually should not be used directly.

5-character name: START

EndTransaction

To indicate the end of a transaction chain.

This is used internally by the poll method to manage transaction stages and usually should not be used directly.

5-character name: ENDTR

Acknowledge

To acknowledge the receipt of a command.

This is used internally by the state machine to manage acknowledgment status and usually should not be used directly.

5-character name: ACKNO

Query

To request the outbound data from the device.

This is used internally by the state machine to manage transaction stages and usually should not be used directly.

5-character name: QUERY

Return

To return the response data from the device to the host.

This is used internally by the state machine to manage transaction stages and usually should not be used directly.

5-character name: RTURN

Empty

To indicate that the current transaction phase has no data.

This is used internally by the state machine to manage transaction stages and usually should not be used directly.

5-character name: EMPTY

Data

To send a chunk of data.

This is used internally by the state machine to manage transaction stages and usually should not be used directly.

5-character name: SDATA

Await

To indicate that the device is still processing and the transaction should be kept alive.

This is used internally by the state machine to manage transaction stages and usually should not be used directly.

5-character name: AWAIT

Error

To indicate an error occurred during transaction processing.

This is used internally by the state machine to manage error handling and usually should not be used directly.

5-character name: ERROR

Implementations

impl Operation

pub fn to_name(&self) -> &'static str

Returns the 5-character string representation of the operation.

pub fn from_name(name: &str) -> Option<Operation>

Creates an Operation from its 5-character string representation.

pub fn is_root(&self) -> bool

Checks if the operation is a “root operation” that can initiate a transaction chain.

Trait Implementations

impl Clone for Operation

fn clone(&self) -> Operation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operation

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

Formats the value using the given formatter.

impl PartialEq for Operation

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

impl Copy for Operation

impl Eq for Operation

impl StructuralPartialEq for Operation
