Methods
impl Symbol
[src]
fn new(string: &str) -> Self
Creates a new instance of Ruby Symbol
.
Examples
use ruru::{Symbol, VM}; let symbol = Symbol::new("hello"); assert_eq!(symbol.to_string(), "hello");
Ruby:
sym = :hello
sym.to_s == 'hello'
fn to_string(&self) -> String
Retrieves the Rust String
corresponding to Symbol
object (Ruby Symbol#to_s
).
Examples
use ruru::{Symbol, VM}; let symbol = Symbol::new("hello"); assert_eq!(symbol.to_string(), "hello");
Ruby:
sym = :hello
sym.to_s == 'hello'
