Struct ThreadPoolConfig 

pub struct ThreadPoolConfig {
    pub timing: PoolSpec,
    pub io: PoolSpec,
    pub workers: usize,
}

Resolved, immutable process-wide thread-pool configuration.

Fields

timing: PoolSpec

Low-jitter periodic dispatch (the cadence scheduler).

io: PoolSpec

Offloaded reporter / report I/O.

workers: usize

The tokio async runtime worker-thread count (consumed by the runtime builder in nmbrs-runtime; the registry does not own that runtime).

Implementations

impl ThreadPoolConfig

pub fn defaults() -> Self

Reasonable defaults derived from the core count (SRD-102 §3): 1 timing thread (RR + auto-pin), 2 io threads, workers = cores − reserved. On < 3 cores the reservation degrades (workers gets at least 1; the timing pin/RR still applies but shares a core — logged at spawn).

pub fn resolve() -> Result<Self, String>

Overlay NMBRS_THREADS_* env vars onto the defaults. Returns Err on a malformed value (never silently ignored). The nmbrs binary layers CLI flags on top of this before calling init.

pub fn resolve_with_cli(cli: &CliThreadOverrides) -> Result<Self, String>

Resolve with CLI --threads.* flags layered on top of env + defaults, giving the CLI > env > defaults precedence of SRD-102 §4. Parsing lives here (not in the nmbrs binary) so a malformed CLI value is the SAME hard error as the env path — via the same SchedPolicy::parse / Affinity::parse and thread-count parsing, never silently coerced.
