[−][src]Struct rutie::Encoding
Methods
impl Encoding
[src]
pub fn utf8() -> Self
[src]
Creates a UTF-8 instance of Encoding
.
Examples
use rutie::{Encoding, VM}; Encoding::utf8();
Ruby:
Encoding::UTF_8
pub fn us_ascii() -> Self
[src]
Creates a US-ASCII instance of Encoding
.
Examples
use rutie::{Encoding, VM}; Encoding::us_ascii();
Ruby:
Encoding::US_ASCII
pub fn default_external() -> Self
[src]
Creates a new instance of Encoding
from the default external encoding.
Examples
use rutie::{Encoding, VM}; Encoding::default_external();
Ruby:
Encoding.default_external
pub fn default_internal() -> Result<Self, NilClass>
[src]
Creates an instance of Ok(Encoding)
from the default internal encoding
if there is one, otherwise it returns Err(NilClass)
.
Examples
use rutie::{Encoding, VM}; Encoding::default_internal();
Ruby:
Encoding.default_internal
pub fn name(&self) -> String
[src]
Returns encoding name.
Examples
use rutie::{RString, Encoding, VM}; let enc = Encoding::utf8(); assert_eq!(enc.name(), "UTF-8")
Ruby:
enc = Encoding::UTF_8
enc.name == "UTF-8"
pub fn find(s: &str) -> Result<Encoding, AnyException>
[src]
Find an Ok(Encoding)
for given string name or return an Err(AnyException)
.
Examples
use rutie::{VM, Encoding}; let encoding = Encoding::find("UTF-8"); match encoding { Ok(enc) => assert_eq!(enc.name(), "UTF-8"), Err(_) => unreachable!() }
Ruby:
encoding = Encoding.find("UTF-8")
encoding.name == "UTF-8"
The following is an example where a Ruby exception object of ArgumentError
is returned.
use rutie::{VM, Encoding, Exception}; let encoding = Encoding::find("UTF8"); match encoding { Ok(_) => unreachable!(), Err(e) => assert_eq!(e.message(), "unknown encoding name - UTF8") }
pub fn is_compatible(
obj1: &impl Object,
obj2: &impl Object
) -> Result<Self, NilClass>
[src]
obj1: &impl Object,
obj2: &impl Object
) -> Result<Self, NilClass>
Returns an instance of Ok(Encoding)
if the objects are
compatible encodings, otherwise it returns Err(NilClass)
.
Examples
use rutie::{Encoding, VM, RString, NilClass}; let utf8 = RString::new_utf8("asdf"); let us_ascii= RString::new_usascii_unchecked("qwerty"); let result = Encoding::is_compatible(&utf8, &us_ascii); assert!(result.is_ok()); let result = Encoding::is_compatible(&utf8, &NilClass::new()); assert!(result.is_err());
