Struct Hosted 

pub struct Hosted<H: 'static> { /* private fields */ }

A loaded blue program whose definitions a host can call.

Implementations

impl<H: 'static> Hosted<H>

pub fn defines(&self, name: &str) -> bool

Whether the program defines a callable named name.

pub fn call( &mut self, name: &str, args: Vec<Value>, host: &mut H, ) -> Result<Value, RunError>

Call the definition name with args.

Errors

RunError::Eval naming the function when it is not defined or is not callable, or with the message it raised.

impl<H: 'static> Hosted<H>

pub fn call_budgeted( &mut self, name: &str, args: Vec<Value>, host: &mut H, budget: Budget, ) -> Result<Value, CallError>

Call the definition name with args under budget, which starts unspent for this call. Running past it is CallError::Exhausted, told apart from a raise.

Errors

CallError: the name is not a function, or the call ran out or raised.

pub fn try_call( &mut self, name: &str, args: Vec<Value>, host: &mut H, ) -> Result<Value, CallError>
