Struct LaneBus 

pub struct LaneBus { /* private fields */ }

Read-only typed bus carrying Flow outputs to lanes for one tick.

Lanes access it through LaneContext::bus and read views via LaneBus::get. The bus itself is constructed by the scheduler at the start of each frame and dropped at the end — its lifetime is strictly tick-scoped.

Implementations

impl LaneBus

pub fn new() -> Self

Creates an empty bus.

pub fn publish<V: Any + Send + Sync>(&mut self, view: V)

Publishes a typed view into the bus. Replaces any existing entry of the same type. Used by Flow execution; not callable from lane code.

pub fn get<V: Any + Send + Sync>(&self) -> Option<&V>

Returns a shared reference to a view by type, or None if no Flow has published one this tick.

pub fn contains<V: Any + Send + Sync>(&self) -> bool

Reports whether a view of the given type is present.

pub fn len(&self) -> usize

Number of views currently published.

pub fn is_empty(&self) -> bool

Whether no views are published.

pub fn clear(&mut self)

Clears all published views. Called by the scheduler between ticks when a bus instance is reused rather than reallocated.

Trait Implementations

impl Debug for LaneBus

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LaneBus

fn default() -> Self

Returns the “default value” for a type.
