Struct StaticArenas 

pub struct StaticArenas<'a, V> {
    pub values: &'a mut [Option<V>],
    pub terminals: &'a mut [Option<V>],
    pub output_scratch: &'a mut [V],
    pub invocation: &'a [Option<V>],
}

Caller-owned execution arenas for StaticExecutor::execute. Firmware provisions each slice once from McuArenaRequirements; the executor grows none of them.

Fields

values: &'a mut [Option<V>]

One live-buffer slot per plan buffer (value_slots).

terminals: &'a mut [Option<V>]

Collected unconnected outputs (terminal_slots).

output_scratch: &'a mut [V]

Per-step output workspace, reused each step (max_step_outputs).

invocation: &'a [Option<V>]

One value per invocation port (invocation_slots).
