Struct rutie::Proc [−][src]
pub struct Proc { /* fields omitted */ }
Proc
(works with Lambda
as well)
Methods
impl Proc
[src]
impl Proc
pub fn call(&self, arguments: Option<&[AnyObject]>) -> AnyObject
[src]
pub fn call(&self, arguments: Option<&[AnyObject]>) -> AnyObject
Calls a proc with given arguments
Examples
#[macro_use] extern crate rutie; use rutie::{Class, Object, Proc, RString}; class!(Greeter); methods!( Greeter, itself, fn greet_rust_with(greeting_template: Proc) -> RString { let name = RString::new_utf8("Rust").to_any_object(); let rendered_template = greeting_template.unwrap().call(Some(&[name])); rendered_template.try_convert_to::<RString>().unwrap() } ); fn main() { Class::new("Greeter", None).define(|itself| { itself.def_self("greet_rust_with", greet_rust_with); }); }
Ruby:
class Greeter
def self.greet_rust_with(greeting_template)
greeting_template.call('Rust')
end
end
greeting_template = -> (name) { "Hello, #{name}!" }
Greeter.greet_rust_with(greeting_template) # => "Hello, Rust!"
pub fn is_lambda(&self) -> bool
[src]
pub fn is_lambda(&self) -> bool
Check if Proc is a lambda
Examples
use rutie::{Object, Proc, VM, VerifiedObject}; let procish = VM::eval("lambda {|a,b| a + b }").unwrap(); assert!(Proc::is_correct_type(&procish), "not Proc!");
Ruby:
procish = lambda {|a,b| a + b }
procish.lambda? # => true
