pub struct App {
    pub phase: AppPhase,
    /* private fields */
}

An application that runs through lifecycles using a session instance.

Fields

phase: AppPhase

Implementations

impl App

pub fn setup_diagnostics(&self)

Setup miette diagnostics by registering error and panic hooks.

pub fn setup_tracing_with_defaults(&self) -> TracingGuard

Setup tracing messages with default options.

pub fn setup_tracing(&self, options: TracingOptions) -> TracingGuard

Setup tracing messages with custom options.

pub async fn run<S, F, Fut>(self, session: S, op: F) -> Result<u8>

where S: AppSession + 'static, F: FnOnce(S) -> Fut + Send + 'static, Fut: Future<Output = AppResult> + Send + 'static,

Start the application with the provided session and execute all phases in order. If a phase fails, always run the shutdown phase.

pub async fn run_with_session<S, F, Fut>( self, session: &mut S, op: F, ) -> Result<u8>

where S: AppSession + 'static, F: FnOnce(S) -> Fut + Send + 'static, Fut: Future<Output = AppResult> + Send + 'static,

Start the application with the provided session and execute all phases in order. If a phase fails, always run the shutdown phase.

This method is similar to App#run but doesn’t consume the session, and instead accepts a mutable reference.

Trait Implementations
