pub struct Encoding { /* private fields */ }
Implementations
sourceimpl Encoding
impl Encoding
sourcepub fn utf8() -> Self
pub fn utf8() -> Self
Creates a UTF-8 instance of Encoding
.
Examples
use rutie::{Encoding, VM};
Encoding::utf8();
Ruby:
Encoding::UTF_8
sourcepub fn us_ascii() -> Self
pub fn us_ascii() -> Self
Creates a US-ASCII instance of Encoding
.
Examples
use rutie::{Encoding, VM};
Encoding::us_ascii();
Ruby:
Encoding::US_ASCII
sourcepub fn default_external() -> Self
pub fn default_external() -> Self
Creates a new instance of Encoding
from the default external encoding.
Examples
use rutie::{Encoding, VM};
Encoding::default_external();
Ruby:
Encoding.default_external
sourcepub fn default_internal() -> Result<Self, NilClass>
pub fn default_internal() -> Result<Self, NilClass>
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
sourcepub fn name(&self) -> String
pub fn name(&self) -> String
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"
sourcepub fn find(s: &str) -> Result<Encoding, AnyException>
pub fn find(s: &str) -> Result<Encoding, AnyException>
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")
}
