Implementations
sourceimpl Symbol
impl Symbol
sourcepub fn new(string: &str) -> Self
pub fn new(string: &str) -> Self
Creates a new instance of Ruby Symbol
.
Examples
use rutie::{Symbol, VM};
let symbol = Symbol::new("hello");
assert_eq!(symbol.to_str(), "hello");
Ruby:
sym = :hello
sym.to_s == 'hello'
sourcepub fn to_str(&self) -> &str
pub fn to_str(&self) -> &str
Retrieves the Rust &str
corresponding to Symbol
object (Ruby Symbol#to_s
).
Examples
use rutie::{Symbol, VM};
let symbol = Symbol::new("hello");
assert_eq!(symbol.to_str(), "hello");
Ruby:
sym = :hello
sym.to_s == 'hello'
