Module storage 

Persistence: a game’s saves and the player’s settings go through Storage, so the UI stays pure. The platform supplies the real implementation (files, the browser’s localStorage, a console’s own files); MemoryStorage is for tests and the test harness.

Structs

MemoryStorage

An in-memory Storage, for tests and the harness. Nothing persists past the process.

Enums

StorageError

Why a Storage operation failed.

Constants

MAX_KEY_LEN

Longest key Storage accepts, in bytes.

Traits

PowerCutRig

A Storage over a fake of its medium, which can lose the power: what a backend writes to run power_cut_suite.

Storage

A place to persist small named blobs of text (RON documents, typically): files on native, localStorage on web.

Functions

conformance_suite

A conformance suite every Storage implementation must pass, shared by this crate’s own tests and the platforms’ implementations.

is_valid_key

Whether key matches ^[a-z0-9_-]{1,64}$: lowercase ASCII letters, digits, _ and -, 1 to MAX_KEY_LEN bytes.

power_cut_suite

Cuts the power in a write over an old value, a first write and a delete, after each number of operations of the medium in turn, until the operation finishes, and checks what the storage reads after each restart. Panics with the promise broken, the operation and the cut.
