Implementations

impl<'a> NodeBuilder<'a>

pub fn name(self, name: impl Into<String>) -> Self

Names the node.

The default name is node ID.

pub fn init<F>(self, new_task: impl Fn() -> F + Send + Sync + 'static) -> Self

where F: Future + 'static,

Set the initial task for the node.

This task will be respawned when calling restart.

pub fn restart_on_panic(self) -> Self

By default a panic will terminate the simulation.

pub fn restart_on_panic_matching(self, msg: impl Into<String>) -> Self

pub fn ip(self, ip: IpAddr) -> Self

Set one IP address of the node.

pub fn cores(self, cores: usize) -> Self

Set the number of CPU cores of the node.

This will be the return value of std::thread::available_parallelism.

pub fn build(self) -> NodeHandle
