Struct ServiceConfig 

pub struct ServiceConfig {
    pub name: String,
    pub description: String,
    pub exec_start: String,
    pub working_directory: Option<String>,
    pub user: Option<String>,
    pub group: Option<String>,
    pub restart: Option<String>,
    pub restart_sec: Option<u32>,
    pub wanted_by: Option<String>,
    pub environment: Option<Vec<(String, String)>>,
    pub after: Option<Vec<String>>,
    pub log_file: Option<String>,
}

Represents the configuration for a systemd service.

Use ServiceConfig::new to create a basic configuration and chain builder methods to set optional parameters.

Fields

name: String

The name of the service (e.g., “myapp”). This is used for the .service filename.

description: String

A brief description of the service (e.g., “My Application Service”).

exec_start: String

The command to execute to start the service (e.g., “/usr/local/bin/myapp –daemon”).

working_directory: Option<String>

The working directory for the service process.

user: Option<String>

The user to run the service as.

group: Option<String>

The group to run the service as.

restart: Option<String>

Restart policy (e.g., “no”, “on-success”, “on-failure”, “always”).

restart_sec: Option<u32>

Delay (in seconds) before restarting the service.

wanted_by: Option<String>

The target to install this service under (usually “multi-user.target”).

environment: Option<Vec<(String, String)>>

Environment variables to set for the service (e.g., vec![("RUST_LOG".to_string(), "info".to_string())]).

after: Option<Vec<String>>

Services that must be started before this one (e.g., vec!["network.target".to_string()]).

log_file: Option<String>

File path to redirect StandardOutput to. StandardError is set to inherit.

Implementations

impl ServiceConfig

pub fn new(name: &str, exec_start: &str, description: &str) -> Self

Sets the working directory for the service (builder method).

pub fn user(self, user: &str) -> Self

Sets the user for the service (builder method).

pub fn group(self, group: &str) -> Self

Sets the group for the service (builder method).

pub fn restart(self, restart: &str) -> Self

Sets the restart policy for the service (builder method).

pub fn restart_sec(self, sec: u32) -> Self

Sets the restart delay (in seconds) for the service (builder method).

pub fn wanted_by(self, target: &str) -> Self

Sets the WantedBy target for the service (builder method).

pub fn environment(self, env: Vec<(String, String)>) -> Self

Sets environment variables for the service (builder method).

pub fn after(self, after: Vec<String>) -> Self

Sets service dependencies (After=) (builder method).

pub fn log_file(self, file_path: &str) -> Self

Sets the log file path for StandardOutput (builder method).
