pub struct SpawnTaskHandle { /* fields omitted */ }

An handle for spawning tasks in the service.

Implementations

impl SpawnTaskHandle

pub fn spawn(
    &self,
    name: &'static str,
    group: impl Into<GroupName>,
    task: impl Future<Output = ()> + Send + 'static
)

Spawns the given task with the given name and a group name. If group is not specified DEFAULT_GROUP_NAME will be used.

Note that the name is a &'static str. The reason for this choice is that statistics about this task are getting reported to the Prometheus endpoint (if enabled), and that therefore the set of possible task names must be bounded.

In other words, it would be a bad idea for someone to do for example spawn(format!("{:?}", some_public_key)).

pub fn spawn_blocking(
    &self,
    name: &'static str,
    group: impl Into<GroupName>,
    task: impl Future<Output = ()> + Send + 'static
)

Spawns the blocking task with the given name. See also spawn.
