pub struct System { /* private fields */ }
Expand description

A manager for a per-thread distributed async runtime.

Implementations§

source§

impl System

source

pub fn new() -> SystemRunner

Available on non-crate feature io-uring only.

Create a new system.

§Panics

Panics if underlying Tokio runtime can not be created.

source

pub fn with_tokio_rt<F>(runtime_factory: F) -> SystemRunner
where F: FnOnce() -> Runtime,

Available on non-crate feature io-uring only.

Create a new System using the Tokio Runtime returned from a closure.

source§

impl System

source

pub fn current() -> System

Get current running system.

§Panics

Panics if no system is registered on the current thread.

source

pub fn try_current() -> Option<System>

Try to get current running system.

Returns None if no System has been started.

Unlike current, this never panics.

source

pub fn arbiter(&self) -> &ArbiterHandle

Get handle to a the System’s initial Arbiter.

source

pub fn is_registered() -> bool

Check if there is a System registered on the current thread.

source

pub fn id(&self) -> usize

Numeric system identifier.

Useful when using multiple Systems.

source

pub fn stop(&self)

Stop the system (with code 0).

source

pub fn stop_with_code(&self, code: i32)

Stop the system with a given exit code.
