Struct Simulation 

pub struct Simulation { /* private fields */ }

Builder for a multi-node simulation topology.

Nodes and links are registered, then start instantiates all engines, creates SimFaces, installs routes, and returns a RunningSimulation handle.

Implementations

impl Simulation

pub fn new() -> Self

pub fn channel_buffer(self, size: usize) -> Self

Set the channel buffer size for SimLinks (default: 256).

pub fn add_node(&mut self, config: EngineConfig) -> NodeId

Add a forwarding node and return its handle.

pub fn link(&mut self, a: NodeId, b: NodeId, config: LinkConfig)

Connect two nodes with a symmetric link.

pub fn add_route(&mut self, node: NodeId, prefix: &str, nexthop_node: NodeId)

Pre-install a FIB route: packets for prefix at node are forwarded toward nexthop_node (via the SimLink face connecting them).

pub async fn start(self) -> Result<RunningSimulation>

Instantiate all engines, create links, install routes, and start.

Trait Implementations

impl Default for Simulation

fn default() -> Self

Returns the “default value” for a type.
