Struct Petting

pub struct Petting {}

Provides the concrete implementation for “petting” a system watchdog.

This struct doesn’t hold any state; its purpose is to implement the PettingTrait for writing heartbeat messages to a watchdog file.

Implementations

impl Petting

pub fn new() -> Petting

Creates a new Petting instance.

This constructor initializes the watchdog petting mechanism. As the Petting struct is stateless, it simply returns an empty instance.

Returns

A new Petting struct.

Trait Implementations

impl PettingTrait for Petting

fn pet(&mut self, watchdog_filename: &str, watchdog_heartbeat: &str)

Writes the heartbeat message to the specified watchdog file.

This concrete implementation of pet uses std::fs::write to write the watchdog_heartbeat string to the watchdog_filename. The result of the file write operation is intentionally ignored, as the system watchdog typically performs its own checks to determine if the heartbeat was received.

Arguments

• watchdog_filename - The path to the watchdog file.
• watchdog_heartbeat - The string message to write as the heartbeat.
