Struct madsim::runtime::NodeBuilder

source · [−]

pub struct NodeBuilder<'a> { /* private fields */ }

Available on madsim only.

Expand description

Builds a node with custom configurations.

Implementations

source

impl<'a> NodeBuilder<'a>

source

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

Names the node.

The default name is node ID.

source

pub fn init<F>(self, future: impl Fn() -> F + Send + Sync + 'static) -> Selfwhere
F: Future + 'static,

Set the initial task for the node.

This task will be respawned when calling restart.

source

pub fn restart_on_panic(self) -> Self

Automatically restart the node when it panics.

By default a panic will terminate the simulation.

source

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

Set one IP address of the node.

source

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.

source

pub fn build(self) -> NodeHandle

Build a node.

impl<T> Downcast for Twhere
T: Any,

source

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more

source

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more

source

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

source

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s. Read more

source

impl<T> DowncastSync for Twhere
T: Any + Send + Sync,

source

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send + 'static>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait. Read more
