Struct MemoryAllocationPool 

pub struct MemoryAllocationPool { /* private fields */ }

MemoryAllocationPool

One host-wide pool over usable application IDs 10..=254. Governance IDs 0..=9 remain excluded. Explicit additional exclusions retain physical custody for unmanaged users; namespace grants never partition this pool.

The pool is immutable bootstrap policy, not durable allocation state. Current, omitted, reserved and retired ledger records independently retain their IDs. It is not inferred from application bytes or slot contents.

Implementations

impl MemoryAllocationPool

pub fn new( authorities: Vec<MemoryAuthority>, exclusions: Vec<MemoryManagerIdRange>, ) -> Result<Self, MemoryAllocationPoolError>

Canonicalize host grants and physical exclusions before bootstrap.

Panics

Panics only if an internal bounded-ID canonicalization invariant is broken.

pub fn authorities(&self) -> &[MemoryAuthority]

Current owner grants, in canonical namespace order.

pub fn excluded_ranges(&self) -> &[MemoryManagerIdRange]

Physical exclusions including the permanent governance reservation.

pub fn contains(&self, id: u8) -> bool

Whether an ID belongs to the shared application pool.

pub fn validate_authority( &self, key: &StableKey, authority: &str, ) -> Result<(), MemoryAllocationPoolError>

Validate current key ownership independently of numeric placement.

pub fn validate_id(&self, id: u8) -> Result<(), MemoryAllocationPoolError>

Validate physical eligibility without granting ownership of a key.
