Enum AgentAccess 

pub enum AgentAccess {
    Exclusive,
    Isolated,
    SharedWorld,
}

An agent’s data-access footprint during Agent::execute, used by the scheduler’s parallel executor to decide which agents may run concurrently.

The default (Exclusive) is the safe fallback: the agent may touch the ECS World mutably (or a shared mutable resource), so it must run serially. Only an agent that provably confines itself to reading the LaneBus and writing its own OutputDeck should declare Isolated.

Variants

Exclusive

Needs exclusive &mut World (or mutates a shared resource); runs serially. The safe default.

Isolated

Touches no World and writes only its own OutputDeck — no shared mutable engine resources. Eligible for concurrent execution: the scheduler runs it with WorldAccess::None and a private deck shard, folded back into the shared deck after the concurrent wave. Any number may run in the same wave.

SharedWorld

Reads the World immutably (never mutates it) and may write shared engine resources. The scheduler runs it with a shared WorldAccess::Shared reference so many world-readers execute concurrently. Because it may write shared resources whose ordering matters, at most one SharedWorld agent runs per wave (alongside any number of Isolated agents).

Trait Implementations

impl Clone for AgentAccess

fn clone(&self) -> AgentAccess

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AgentAccess

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

Formats the value using the given formatter.

impl Default for AgentAccess

fn default() -> AgentAccess

Returns the “default value” for a type.

impl PartialEq for AgentAccess

fn eq(&self, other: &AgentAccess) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
