Trait InnerValue 

pub trait InnerValue {
    type Value: ReprValue;

    // Required method
    fn get_inner_with(self, ruby: &Ruby) -> Self::Value;
}

Helper trait for Ruby::get_inner.

This trait allows for Ruby::get_inner to get the inner value of both Opaque and Lazy.

Required Associated Types

type Value: ReprValue

The specific Ruby value type.

Required Methods

fn get_inner_with(self, ruby: &Ruby) -> Self::Value

Get the inner value from self.

ruby acts as a token proving this is called from a Ruby thread and thus it is safe to return the inner value.

Examples

use magnus::{
    rb_assert,
    value::{InnerValue, Opaque},
    Ruby,
};

let ruby = Ruby::get().unwrap();
let opaque_str = Opaque::from(ruby.str_new("example"));

// send to another Ruby thread

let ruby = Ruby::get().unwrap(); // errors on non-Ruby thread
let str = opaque_str.get_inner_with(&ruby);
rb_assert!(ruby, r#"str == "example""#, str);

use magnus::{
    rb_assert,
    value::{InnerValue, Lazy},
    RString, Ruby,
};

static STATIC_STR: Lazy<RString> = Lazy::new(|ruby| ruby.str_new("example"));

let ruby = Ruby::get().unwrap(); // errors if Ruby not initialised
let str = STATIC_STR.get_inner_with(&ruby);
rb_assert!(ruby, r#"str == "example""#, str);
