Struct RuntimeConfig 

pub struct RuntimeConfig {
    pub workers: usize,
    pub quantum: u32,
    pub mailbox: MailboxConfig,
    pub max_flows: u32,
    pub trust: TrustLevel,
    pub output: Arc<dyn OutputSink>,
    pub quota: QuotaConfig,
    pub jit: JitConfig,
}

Tunables for Runtime::new. Everything has a sensible default via RuntimeConfig::default so the common case is Runtime::new(chunk).

Fields

workers: usize

Number of worker OS threads. Defaults to the number of logical CPUs — one worker per core is the right starting point for a CPU-bound M:N scheduler; embedders running alongside other CPU-heavy work on the same machine may want fewer.

quantum: u32

Instructions a flow runs before being preempted back to the scheduler even if it never hits Yield.

mailbox: MailboxConfig

Memory + overflow contract applied to every flow mailbox spawned by this runtime (bytecode Spawn and host spawn). See MailboxConfig / docs/mailbox.md.

max_flows: u32

Hard cap on concurrently live flows (0 = unlimited). Checked on every host and bytecode spawn.

trust: TrustLevel

Constant-pool trust for crate::verify_with at runtime construction. Default is crate::TrustLevel::Untrusted (fail closed).

output: Arc<dyn OutputSink>

Where bytecode print (native index 0) writes when using crate::std_native_table_with. Ignored if you supply your own table.

quota: QuotaConfig

Per-flow CPU / memory / spawn-send rate budgets.

jit: JitConfig

Available on crate feature jit only.

Trace JIT settings (feature = "jit"). Ignored when the feature is off.
