Struct MemoryManagerRangeAuthority 

pub struct MemoryManagerRangeAuthority { /* private fields */ }

MemoryManagerRangeAuthority

Substrate-specific range authority policy helper for MemoryManager IDs.

This helper records policy and diagnostic authority ranges only. It never mutates the allocation ledger, and it does not allocate or reserve durable stable-memory slots. Durable allocation remains the generic ledger mapping from stable key to allocation slot.

When used through the default runtime registry, registered ranges are authoritative generic policy and are checked before caller-supplied crate::AllocationPolicy. When no user ranges are registered, frameworks can enforce fixed application claims through their own policy. Logical placement and historical selection always require explicit grants; fresh placements use only Allowed ranges.

Implementations

impl MemoryManagerRangeAuthority

pub const fn new() -> Self

Create an empty MemoryManager range authority policy.

pub fn from_records( records: Vec<MemoryManagerAuthorityRecord>, ) -> Result<Self, MemoryManagerRangeAuthorityError>

Build a range authority from diagnostic records.

Records already carry checked bounds and metadata. Reject overlaps in input order and retain accepted records in ascending range order in the supplied buffer.

pub fn validate_slot_authority( &self, slot: &MemoryManagerSlot, expected_authority: &str, ) -> Result<&MemoryManagerAuthorityRecord, MemoryManagerRangeAuthorityError>

Validate that slot belongs to expected_authority.

pub fn validate_slot_authority_mode( &self, slot: &MemoryManagerSlot, expected_authority: &str, expected_mode: MemoryManagerRangeMode, ) -> Result<&MemoryManagerAuthorityRecord, MemoryManagerRangeAuthorityError>

Validate that slot belongs to expected_authority with expected_mode.

pub fn validate_id_authority( &self, id: u8, expected_authority: &str, ) -> Result<&MemoryManagerAuthorityRecord, MemoryManagerRangeAuthorityError>

Validate that id belongs to expected_authority.

pub fn validate_id_authority_mode( &self, id: u8, expected_authority: &str, expected_mode: MemoryManagerRangeMode, ) -> Result<&MemoryManagerAuthorityRecord, MemoryManagerRangeAuthorityError>

Validate that id belongs to expected_authority with expected_mode.

pub fn authority_for_id( &self, id: u8, ) -> Result<Option<&MemoryManagerAuthorityRecord>, MemoryManagerRangeAuthorityError>

Return the authority record that governs id, if any.

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

Ordered non-overlapping authority records.

This is the stable diagnostic/export surface for the authority table. Records are returned in ascending range order and do not imply ledger allocation state.

pub fn validate_complete_coverage( &self, target: MemoryManagerIdRange, ) -> Result<(), MemoryManagerRangeAuthorityError>

Validate that authority records exactly and contiguously cover target.

All records must be inside target, and together they must form a gap-free partition. This checks policy table coverage only and never changes allocation ledger state.
