Struct SubMain 

pub struct SubMain<'m> { /* private fields */ }

A sub-main instance, which can be used to contribute global tasks to the main instance which created this sub instance, but gather own tasks, which can be run independently by calling the SubMain::run function.

Implementations

impl SubMain<'_>

pub fn is_empty(&self) -> bool

Returns true is there are no tasks scheduled so far.

pub fn sub_main(&self) -> SubMain<'_>

Create a new sub-main instance.

pub fn sub_main_seed(&self) -> SubMainSeed

Create a seed or a sub-main instance, which can be sent.

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

Run the recorded tasks.

NOTE: This does not run any health checks, these must be run by the main instance.

Trait Implementations

impl<'m> Extend<Pin<Box<dyn Future<Output = Result<(), Error>> + 'm>>> for SubMain<'m>

fn extend<T: IntoIterator<Item = LocalBoxFuture<'m, Result<()>>>>( &mut self, iter: T, )

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)
