Struct BudgetShares 

pub struct BudgetShares { /* private fields */ }

The resolved per-pool shares of one process budget.

Implementations

impl BudgetShares

pub fn resolve(budget: MemoryBudget, profile: DeployProfile) -> BudgetShares

Divide a resolved budget among the pools.

Integer division comes first (budget / 10_000 then * basis_points) for two reasons: budget * basis_points overflows u64 for budgets above ~1.8 EiB, and dividing first makes Σ(shares) ≤ budget an identity rather than a rounding accident. The cost is at most 9_999 bytes of unallocated remainder per pool.

pub fn budget_bytes(&self) -> u64

The budget these shares divide.

pub fn policy(&self) -> BudgetSharePolicy

The policy that produced these shares.

pub fn share_bytes(&self, pool: MemoryPool) -> u64

This pool’s slice of the budget.

pub fn total_share_bytes(&self) -> u64

Σ(shares). Never exceeds Self::budget_bytes.

pub fn page_cache_slots(&self) -> usize

Page-cache slot count: the share divided by the fixed page size.

Clamped to the cache’s structural minimum. A budget small enough to hit the clamp buys a page cache slightly larger than its share; that is visible in red.stats as used_bytes > share_bytes and, per ADR 0073 §4, is the enforcement slice’s problem, not this one’s.

pub fn blob_cache_l1_bytes(&self) -> usize

Blob Cache L1 byte ceiling: the RAM tier’s share, verbatim.

pub fn log_once(&self)

Emit one boot log line per pool naming its share. Guarded so a process that opens several runtimes still logs exactly once, matching memory_budget::log_resolved_once.
