Methods
impl RString
[src]
impl RString
pub fn new(string: &str) -> Self
[src]
pub fn new(string: &str) -> Self
Creates a new instance of Ruby String
containing given string
.
Examples
use rutie::{RString, VM}; let string = RString::new("Hello, World!"); assert_eq!(string.to_str(), "Hello, World!");
Ruby:
str = 'Hello, World!'
str == 'Hello, World!'
pub fn new_utf8(string: &str) -> Self
[src]
pub fn new_utf8(string: &str) -> Self
Creates a new instance of Ruby String
, with UTF8 encoding, containing
given string
.
Examples
use rutie::{RString, VM}; let string = RString::new_utf8("Hello, World!"); assert_eq!(string.to_string(), "Hello, World!".to_string());
Ruby:
str = 'Hello, World!'
str == 'Hello, World!'
pub fn to_string(&self) -> String
[src]
pub fn to_string(&self) -> String
Retrieves underlying Rust String
from Ruby String
object.
Examples
use rutie::{RString, VM}; let string = RString::new("Hello, World!"); assert_eq!(string.to_string(), "Hello, World!".to_string());
Ruby:
str = 'Hello, World!'
str == 'Hello, World!'
pub fn to_string_unchecked(&self) -> String
[src]
pub fn to_string_unchecked(&self) -> String
Retrieves underlying Rust String
from Ruby String
object.
Unlike to_string()
it does not perform any checks for internal null-bytes.
This function may be used to safely get binary data from Ruby.
Examples
use rutie::{RString, VM}; let string = RString::new("Hello,\0World!"); assert_eq!(string.to_string_unchecked(), "Hello,\0World!".to_string());
Ruby:
str = 'Hello,\0World!'
str == 'Hello,\0World!'
pub fn to_vec_u8_unchecked(&self) -> Vec<u8>
[src]
pub fn to_vec_u8_unchecked(&self) -> Vec<u8>
Retrieves Vec<u8>
from Ruby String
object.
Unlike to_string()
it does not perform any checks for internal null-bytes.
This function may be used to safely get binary data from Ruby.
Examples
use rutie::{RString, VM}; let string = RString::new("Hello,\0World!"); assert_eq!(string.to_vec_u8_unchecked(), (b"Hello,\0World!").to_vec());
pub fn to_str(&self) -> &str
[src]
pub fn to_str(&self) -> &str
Retrieves underlying &str
from Ruby String
object.
Examples
use rutie::{RString, VM}; let string = RString::new("Hello, World!"); assert_eq!(string.to_str(), "Hello, World!");
Ruby:
str = 'Hello, World!'
str == 'Hello, World!'
pub fn to_str_unchecked(&self) -> &str
[src]
pub fn to_str_unchecked(&self) -> &str
Retrieves underlying &str
from Ruby String
object.
Unlike to_str()
it does not perform any checks for internal null-bytes.
This function may be used to safely get binary data from Ruby.
Examples
use rutie::{RString, VM}; let string = RString::new("Hello,\0World!"); assert_eq!(string.to_str_unchecked(), "Hello,\0World!");
Ruby:
str = 'Hello,\0World!'
str == 'Hello,\0World!'
pub fn to_bytes_unchecked(&self) -> &[u8]
[src]
pub fn to_bytes_unchecked(&self) -> &[u8]
Retrieves underlying &[u8]
from Ruby String
object.
Unlike to_str()
it does not perform any checks for internal null-bytes.
This function may be used to safely get binary data from Ruby.
Examples
use rutie::{RString, VM}; let string = RString::new("Hello,\0World!"); assert_eq!(string.to_bytes_unchecked(), b"Hello,\0World!");
pub fn bytesize(&self) -> i64
[src]
pub fn bytesize(&self) -> i64
Returns the length of the string in bytes
Examples
use rutie::{RString, VM}; let string = RString::new("Hello, World!"); let utf8_string = RString::new("⓯"); assert_eq!(string.bytesize(), 13); assert_eq!(utf8_string.bytesize(), 3);
Ruby:
string = 'Hello, World!'
utf8_string = '⓯'
string.bytesize == 13
utf8_string.bytesize == 3
