Struct ScriptBuilder 

pub struct ScriptBuilder<O: PineOutput> { /* private fields */ }

Implementations

impl<O: PineOutput> ScriptBuilder<O>

pub fn with_code(source: &str) -> ScriptBuilder<O>

pub fn with_inputs(self, inputs: HashMap<String, InputValue>) -> Self

Host overrides for the script’s input.* calls, keyed by input title. Each input.* returns (and validates) the override for its title if one is present, else its declared default. See inputs_from_json.

pub fn with_custom_variables(self, variables: HashMap<String, Value<O>>) -> Self

Host-supplied variables the script can reference, registered as consts alongside the builtin namespaces.

pub fn with_library_loader(self, loader: Box<dyn LibraryLoader>) -> Self

Resolves import statements. Without one, importing a library fails.

pub fn with_request_provider(self, provider: Box<dyn DataProvider>) -> Self

Supplies bars for request.security. Without one, request.security returns na.

pub fn with_broker(self, factory: Box<dyn BrokerFactory>) -> Self

Swaps the broker a strategy trades against. Without one, the built-in DefaultBrokerFactory is used.

pub fn with_ticker(self, ticker: String) -> Self

pub fn with_timeframe(self, timeframe: Timeframe) -> Self

The chart timeframe exposed to the script as timeframe.*. Without one, the namespace is populated with defaults.

pub fn with_bar_count(self, bar_count: usize) -> Self

Run over only the last bar_count bars of the feed. Without one, the whole feed is used.

pub fn with_data(self, data: Data) -> Self

The market to run over: the bars, and the symbol and timeframe they belong to.

The data describes itself, so it fills in syminfo.* and timeframe.* too. An explicit [ScriptBuilder::with_syminfo] or ScriptBuilder::with_timeframe still wins, whichever order they are called in.

pub fn compile(self) -> Result<Script<O>, Error>

where O: LogOutput + PlotOutput + LabelOutput + BoxOutput + InputOutput + LineOutput + TableOutput + MetadataOutput + GlobalOutput + AlertConditionOutput + FillOutput + DrawingOutput,
