Module adapter 

Supported upstream collections with governed memory and an explicit API.

Constructors preserve upstream initialization, panic and persisted-format contracts. These wrappers expose neither raw memory nor unrestricted upstream collections. Use distinct admitted allocations for owning collections. Region views retain a shared lease for disjoint application frames and reload roots per operation. Drop collections and all shared lease owners before reopening. IC Memory enforces one live lease per allocation within each runtime; hosts retain exclusive custody of the backing across runtimes.

Modules

storable

Exact substrate interfaces for backing bounds and record codecs. Implementing Memory grants no allocation authority; constructors require committed RuntimeMemory leases. Explicit upstream storable identities used by the storage adapter.

Structs

BTreeMapRegion

A B-tree view inside one existing, governed allocation lease.

BoundedCell

A stable cell whose writes enforce the record’s declared Storable bound.

StableBTreeMap

Governed upstream BTreeMap; initialization and failures follow upstream contracts.

StableBTreeSet

Governed upstream BTreeSet; initialization and failures follow upstream contracts.

StableCell

StableCell

StableLog

Governed upstream Log; initialization and failures follow upstream contracts.

StableMinHeap

Governed upstream MinHeap; initialization and failures follow upstream contracts.

StableVec

Governed upstream Vec; initialization and failures follow upstream contracts.

Enums

Bound

Exact substrate interfaces for backing bounds and record codecs. Implementing Memory grants no allocation authority; constructors require committed RuntimeMemory leases. States whether the type’s size is bounded or unbounded.

LogWriteError

RegionGrowError

RegionGrowError

Traits

Memory

Exact substrate interfaces for backing bounds and record codecs. Implementing Memory grants no allocation authority; constructors require committed RuntimeMemory leases. Abstraction over a WebAssembly-style linear memory (e.g., stable memory).

Storable

Exact substrate interfaces for backing bounds and record codecs. Implementing Memory grants no allocation authority; constructors require committed RuntimeMemory leases. A trait with convenience methods for storing an element into a stable structure.

Type Aliases

LogIter

Upstream log iterator with governed index and data memories.

MapIter

Upstream map iterator with governed memory.

SetIter

Upstream set iterator with governed memory.
