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