Struct DaemonBuilder 

pub struct DaemonBuilder { /* private fields */ }

Builder for creating daemon instances with fluent API.

Implementations

impl DaemonBuilder

pub fn new(config: Config) -> Self

Create a new daemon builder with the provided configuration.

pub fn with_signal_config(self, config: SignalConfig) -> Self

Configure signal handling.

pub const fn without_signals(self) -> Self

Disable signal handling.

pub fn with_signals(self, sigterm: bool, sigint: bool) -> Self

Enable only specific signals.

pub fn with_task<F, Fut>(self, name: &str, task_fn: F) -> Self

where F: Fn(ShutdownHandle) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<()>> + Send + 'static,

Add a task that will be run as part of the daemon.

A task is a function that will be executed repeatedly until shutdown is requested.

Arguments

• name - Name of the task for identification
• task_fn - Function that implements the task logic

Returns

Updated builder instance

pub fn with_subsystem<S>(self, subsystem: S) -> Self

where S: Subsystem + Send + Sync + 'static,

Add a subsystem that will be managed by the daemon.

A subsystem is a component that implements the Subsystem trait.

Arguments

• subsystem - The subsystem to add

Returns

Updated builder instance

pub fn with_subsystem_fn<F>(self, name: &str, register_fn: F) -> Self

where F: FnOnce(&SubsystemManager) -> SubsystemId + Send + 'static,

Add a subsystem using a registration function.

This is a lower-level method that gives direct access to the SubsystemManager for registration. It’s useful when you need more control over the registration process.

Arguments

• name - Name for identification in logs
• register_fn - Function that handles the subsystem registration

Returns

Updated builder instance

pub fn build(self) -> Result<Daemon>

Build the daemon instance. Builds a daemon from the configured builder

Errors

Returns an error if the daemon configuration is invalid or if required components cannot be initialized

pub async fn run(self) -> Result<()>

Build and run the daemon in one step. Runs the daemon until completion or error

Errors

Returns an error if the daemon encounters an unrecoverable error during execution
