Struct TierThresholds 

pub struct TierThresholds {
    pub t1: u32,
    pub t2: u32,
    pub t3: u32,
}

Call/back-edge counts at which a unit enters each tier (HOTSWAP §5). Defaults: don’t optimize code that runs once (T1 at 8); amortize whole-function analyses only once recurring (T2 at 32); pay the cloning passes only on genuinely hot kernels (T3 at 100, aligned with the existing native-tier threshold).

Fields

t1: u32

t2: u32

t3: u32

Implementations

impl TierThresholds

pub fn tier_for(self, count: u32) -> Tier

The tier a unit with count accumulated calls/back-edges has earned.

pub fn from_env() -> Self

LOGOS_TIER_THRESHOLDS="8,32,100", overridable per-rung by LOGOS_TIER_T1/T2/T3.

pub fn from_spec( combined: Option<&str>, t1: Option<&str>, t2: Option<&str>, t3: Option<&str>, ) -> Self

The pure, testable core of from_env.

Trait Implementations

impl Clone for TierThresholds

fn clone(&self) -> TierThresholds

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TierThresholds

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

Formats the value using the given formatter.

impl Default for TierThresholds

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TierThresholds

fn eq(&self, other: &TierThresholds) -> 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.
