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. Every retained ledger record independently retains its ID, including omitted keys. It is not inferred from application bytes or slot contents.

Construct inputs with Self::new; serialization is for diagnostic output. Decoding is available only with test-support for explicit fixtures.

Implementations

impl MemoryAllocationPool

pub fn new( authorities: Vec<MemoryAuthority>, exclusions: Vec<u8>, ) -> Result<Self, MemoryAllocationPoolError>

Canonicalize host grants and physical exclusions before bootstrap.

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

Current owner grants, in canonical namespace order.

pub fn excluded_ids(&self) -> impl Iterator<Item = u8> + '_

Excluded usable IDs, including governance, in ascending order.

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 authority_for_key(&self, key: &StableKey) -> Option<&str>

Borrow the current namespace grant for a checked key. This does not establish commitment, historical ownership or caller authentication.

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

Validate physical eligibility without granting ownership of a key.
