Struct TierPolicy 

pub struct TierPolicy {
    pub hot_timeout: Duration,
    pub warm_timeout: Duration,
    pub cold_timeout: Duration,
    pub hot_max_output: usize,
    pub warm_max_output: usize,
    pub cold_max_output: usize,
}

Per-tier budgets used when constructing CallContext for a tool call. Warm defaults match the pre-SP-12 server config (1 MiB / 60 s) to keep the 9 existing tools’ behavior unchanged.

Fields

hot_timeout: Duration

warm_timeout: Duration

cold_timeout: Duration

hot_max_output: usize

warm_max_output: usize

cold_max_output: usize

Implementations

impl TierPolicy

pub fn defaults() -> Self

Canonical defaults:

• Hot: 500 ms / 64 KiB — latency-critical tools (sensors, cached state).
• Warm: 5 s / 1 MiB — typical tool invocations (current server default).
• Cold: 60 s / 16 MiB — long-running / large-output tools.

pub fn timeout(&self, tier: ToolTier) -> Duration

pub fn max_output(&self, tier: ToolTier) -> usize

pub fn apply_override(&mut self, spec: &str) -> Result<(), String>

Apply a single "<tier>=<key>=<value>" override. Keys: timeout_ms, max_output_bytes. Returns a human-readable error on malformed input so the CLI can surface it via exit 2.

Trait Implementations

impl Clone for TierPolicy

fn clone(&self) -> TierPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TierPolicy

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

Formats the value using the given formatter.

impl Default for TierPolicy

fn default() -> Self

Returns the “default value” for a type.
