Modules

• config
  A collection of (de-)serializable structs which capture the application state, suitable for persistence, history, etc. features.
• proto
• utils
• vendor

Macros

• assert_table_api
  Assert that an implementation of domain language wrapper for Table implements the expected API. As domain languages have different API needs, a trait isn’t useful for asserting that the entire API is implemented, because the signatures will not match exactly (unless every method is made heavily generic). Instead, this macro complains when a method name is missing.
• assert_view_api
  Similar to assert_table_api, but for View. See assert_table_api.
• clone
  A helper to for the pattern let x2 = x; necessary to clone structs destined for an async or 'static closure stack. This is like move || { .. } or move async { .. }, but for clone semantics. clone!() works with symbols as well as properties and methods, using the last symbol name in the method chain, or an alias via x = ... syntax.

Structs

• Client
  An instance of a Client is a unique connection to a single Server, whether locally in-memory or remote over some transport like a WebSocket. To create, use the appropriate constructor function:
• OnUpdateOptions
• ProxySession
  A Session implementation which tunnels through another Client.
• Table
  Table is Perspective’s columnar data frame, analogous to a Pandas DataFrame or Apache Arrow. Table supports appending data, in-place updates, removal by index, and notifications on update.
• TableInitOptions
  Options which impact the behavior of Client::table, as well as subsequent calls to Table::update, even though this latter method itself does not take TableInitOptions as an argument, since this parameter is fixed at creation.
• UpdateOptions
• ValidateExpressionsData
• View
• ViewWindow

Enums

• OnUpdateMode
• TableData
  The possible formats of input data which [Client::table] may take as an argument.
• UpdateData
  The possible formats of input data which [Table::update] may take as an argument.

Traits

• ClientHandler
• Session
  The server-side representation of a connection to a [perspective_client::Client]. For each [perspective_client::Client] that wants to connect to a [Server], a dedicated Session must be created. The Session handles routing messages emitted by the [Server], as well as owning any resources the Client may request.

Type Aliases

• Features
  Metadata about what features are supported by the Server this Client is connected to.
• Schema
