Struct ServerManager

pub struct ServerManager<F> { /* private fields */ }

Title: ServerManager structure for managing the server process

Parameters:

• None

Returns:

• None

This structure encapsulates the server management operations and holds the user-provided configuration and the server function.

Implementations

impl<F, Fut> ServerManager<F>

where F: Fn() -> Fut, Fut: Future<Output = ()>,

pub fn new(config: ServerConfig, server_fn: F) -> Self

Title: Create a new ServerManager instance

Parameters:

• config: The server configuration containing PID file path and log paths.
• server_fn: A closure representing the asynchronous server function.

Returns:

• ServerManager<F>: A new instance of ServerManager.

pub async fn start(&self)

Title: Start the server in foreground mode

Parameters:

• None

Returns:

• (): No return value.

This function writes the current process ID to the PID file specified in the configuration and then runs the server function asynchronously.

pub fn stop(&self) -> Result<(), Box<dyn Error>>

Title: Stop the server

Parameters:

• None

Returns:

• Result<(), Box<dyn std::error::Error>>: Operation result.

This function reads the process ID from the PID file and attempts to kill the process using a SIGTERM signal.

pub fn start_daemon(&self) -> Result<(), Box<dyn Error>>

Title: Start the server in daemon (background) mode on Unix platforms

Parameters:

• None

Returns:

• Result<(), Box<dyn std::error::Error>>: Operation result.

This function uses the daemonize crate to run the server process in the background. It configures the PID file, stdout log, and stderr log paths from the configuration.
