Crate wickra_terminal_core 

wickra-terminal-core

The data-driven core of the Wickra trading terminal. It folds market events into an O(1) AppState and turns panels into view-models — plain data (values, series, sides), never renderer commands. Two reference renderers consume those view-models (a native TUI and a Web app), and the same core is exposed as a JSON data API in ten languages.

Shape

• DataSource unifies the feed modules (Live, Replay, Synth) behind one symbol-tagged poll().
• AppState::fold applies one event incrementally; nothing is recomputed over history.
• Panel maps state to a PanelView; a Frame is the set of them.
• Terminal ties it together, with Terminal::command_json as the data-driven FFI boundary the bindings drive.

use wickra_terminal_core::{Config, SourceSpec, Terminal, Symbol};

let mut cfg = Config::default_layout();
cfg.sources = vec![SourceSpec::Synth { seed: 1 }];
let mut term = Terminal::new(&cfg).unwrap();
term.subscribe(0, &Symbol::new("BTC", "USDT")).unwrap();
let frame = term.tick();
assert_eq!(frame.panels.len(), 5);

Modules

candle

Tick-to-OHLCV aggregation.

config

The terminal configuration — the data-driven description of what to show.

error

The crate error type.

panels

Panels — pure functions from state to a view-model.

registry

Indicator registry: constructs wickra-core indicators by name and wraps them behind a uniform, object-safe TickIndicator the terminal can drive from one tick.

source

Data sources — the activatable feed modules behind one trait.

state

The terminal’s application state — folded from events in O(1) per event.

terminal

The Terminal handle — the single entry point every renderer and every language binding drives.

view

View-models — the renderer-agnostic output of the core.

Structs

Symbol

A canonical, venue-neutral market: a base asset against a quote asset.

Enums

Event

An item yielded by a pull-based stream.

Functions

version

The crate version (the same string Terminal::version returns).
