Rust
The native crate. Build a Terminal from a Config, subscribe a symbol, then pull frames with tick / command_json.
Two crates, and which one you want depends on what you are building. wickra-terminal is the TUI binary, so it is installed rather than added as a dependency; terminal-core is the library the snippet below uses.
Pre-release
Nothing is published yet. The terminal depends on wickra-exchange as a git dependency and cargo publish rejects those, so the first release waits on that crate reaching crates.io. What follows is what installing will look like; until then, build from source.
bash
cargo install wickra-terminal # the native TUI
cargo add terminal-core # the core, to build your own front-endrust
use terminal_core::{Config, SourceSpec, Symbol, Terminal};
let mut config = Config::default_layout();
config.sources = vec![SourceSpec::Synth { seed: 1 }];
let mut terminal = Terminal::new(&config).expect("valid config");
terminal.subscribe(0, &Symbol::new("BTC", "USDT")).expect("subscribe");
for _ in 0..20 {
terminal.tick();
}
let frame = terminal.command_json("{\"type\":\"Tick\"}").expect("tick");
println!("{frame}");
