Implementations
sourceimpl Extensions
impl Extensions
sourcepub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns whether there are no extensions present.
Examples
use icu::locid::Locale;
let loc: Locale = "en-US-u-foo".parse()
.expect("Parsing failed.");
assert_eq!(loc.extensions.is_empty(), false);
sourcepub fn retain_by_type<F>(&mut self, predicate: F) where
F: FnMut(ExtensionType) -> bool,
pub fn retain_by_type<F>(&mut self, predicate: F) where
F: FnMut(ExtensionType) -> bool,
Retains the specified extension types, clearing all others.
Examples
use std::str::FromStr;
use icu::locid::Locale;
use icu::locid::extensions::ExtensionType;
let loc: Locale = "und-a-hello-t-mul-u-world-z-zzz-x-extra".parse().unwrap();
let mut only_unicode = loc.clone();
only_unicode.extensions.retain_by_type(|t| t == ExtensionType::Unicode);
assert_eq!(only_unicode, "und-u-world");
let mut only_t_z = loc.clone();
only_t_z.extensions.retain_by_type(|t| {
t == ExtensionType::Transform
|| t == ExtensionType::Other(b'z')
});
assert_eq!(only_t_z, "und-t-mul-z-zzz");

sourceimpl Writeable for Extensions
impl Writeable for Extensions
sourcefn write_to<W: Write + ?Sized>(&self, sink: &mut W) -> Result
fn write_to<W: Write + ?Sized>(&self, sink: &mut W) -> Result
Writes bytes to the given sink. Errors from the sink are bubbled up.
The default implementation delegates to write_to_parts
, and discards any
Part
annotations. Read more

Write bytes and Part
annotations to the given sink. Errors from the
sink are bubbled up. The default implementation delegates to write_to
,
and doesn’t produce any Part
annotations. Read more
