Struct LiveRunner 

pub struct LiveRunner { /* private fields */ }

Runs the code of a Playground with the interpreter: its first function, which returns impl View, is called and shown. The program’s own use lines are read and left alone; what it does not read comes back as diagnostics with their place.

use ravenrs_widgets::{LiveRunner, Runner};

let view = LiveRunner::new().run(r#"fn hello() -> impl View { Text::new("hello") }"#);
assert!(view.is_ok());

Implementations

impl LiveRunner

pub fn new() -> LiveRunner

A runner over live_registry.

pub fn with_registry(registry: Registry) -> LiveRunner

A runner over a registry of the app’s own, such as one with more types added.

Trait Implementations

impl Clone for LiveRunner

fn clone(&self) -> LiveRunner

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LiveRunner

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for LiveRunner

fn default() -> LiveRunner

Returns the “default value” for a type.

impl Runner for LiveRunner

fn run(&self, source: &str) -> Result<Box<dyn View>, Vec<CodeDiagnostic>>

The view source makes, or where and why it cannot make one.

fn take_output(&self) -> RunOutput

What the code printed, and the problems of what it runs later, such as a closure on a click, since the last time this was asked. Nothing, unless the runner keeps them.

fn watch(&self, wake: Rc<dyn Fn()>)

Calls wake whenever there is something new for Self::take_output, so the playground shows it as it comes. Nothing, unless the runner can tell.
