Struct ruru::Proc
[−]
[src]
pub struct Proc { // some fields omitted }
Proc
(works with Lambda
as well)
Methods
impl Proc
[src]
fn call(&self, arguments: Vec<AnyObject>) -> AnyObject
Calls a proc with given arguments
Examples
#[macro_use] extern crate ruru; use ruru::{Class, Proc, RString}; use ruru::traits::Object; class!(Greeter); methods!( Greeter, itself, fn greet_rust_with(greeting_template: Proc) -> RString { let name = RString::new("Rust").to_any_object(); greeting_template.call(vec![name]).to::<RString>() } ); fn main() { Class::new("Greeter").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!"
