Modules

client

errors

migration

observability

What a running program can say about its own state.

prelude

What an ordinary program needs, in one import.

reactive

Reactive primitives: values that persist and notify.

schema

What this binary declares, collected at link time.

shape

What a declared field’s type is, answered by the compiler.

store

stores

Macros

migrate_field

Structs

AlreadyInstalled

A store handed to install_global while another open one was in place, handed back untouched.

Change

GlobalStoreGuard

Closes the process-wide store when it goes out of scope.

Id

A key that is not a string, spelled once and kept that way.

ReactiveScope

Subscriptions held together, ending when the scope does.

SignalSubscription

Dropping this ends the subscription, so it has to be held for as long as the callback should keep firing. ReactiveScope is where several are held together.

Enums

InitGlobal

Why the process-wide store was not put in place.

MapChange

Traits

IntoGlobalStore

ReactiveMapKey

ReactiveMapValue

Functions

global_store

The process-wide store.

init_global

Opens the process-wide store.

install_global

Puts a store that is already open in place as the process-wide one.

shutdown

Closes the process-wide store: writes what it still holds, stops its background thread and lets go of the file.

shutdown_async

shutdown, awaited rather than blocked on: the closing write runs without holding the thread that awaits it.

Type Aliases

AmeData

MigrationResult

What a migration step answers with: everything it can fail at, and nothing else.

StorageResult

Attribute Macros

amethystate

Generates a persistent state wrapper for a struct.

migrate

Declares a migration step, discovered wherever it is written.
