APIs to manage stable memory.

You can check the Internet Computer Specification for a in-depth explanation of stable memory.

Structs§

BufferedStableReader: A reader to the stable memory which reads bytes a chunk at a time as each chunk is required.
BufferedStableWriter: A writer to the stable memory which first writes the bytes to an in memory buffer and flushes the buffer to stable memory each time it becomes full.
CanisterStableMemory: A standard implementation of StableMemory.
StableIO: Performs generic IO (read, write, and seek) on stable memory.
StableReader: Keeps an offset and reads off stable memory consecutively.
StableWriter: A writer to the stable memory.

StableMemory: A trait defining the stable memory API which each canister running on the IC can make use of

stable64_grow: Similar to stable_grow but with support for 64-bit addressed memory.
stable64_read: Similar to stable_read but with support for 64-bit addressed memory.
stable64_size: Similar to stable_size but with support for 64-bit addressed memory.
stable64_write: Similar to stable_write but with support for 64-bit addressed memory.
stable_bytes: Returns a copy of the stable memory.
stable_grow: Attempts to grow the stable memory by new_pages (added pages).
stable_read: Reads data from the stable memory location specified by an offset.
stable_size: Gets current size of the stable memory (in WASM pages).
stable_write: Writes data to the stable memory location specified by an offset.
