Struct icu::experimental::transliterate::RuleCollection
source · pub struct RuleCollection { /* private fields */ }
Expand description
A collection of transliteration rules.
✨ Enabled with the compile
Cargo feature.
§Example
use icu::experimental::transliterate::{RuleCollection, Transliterator};
let mut collection = RuleCollection::default();
collection.register_source(
&"de-t-de-d0-ascii".parse().unwrap(),
r#"
$AE = [Ä {A \u0308}];
$OE = [Ö {O \u0308}];
$UE = [Ü {U \u0308}];
[ä {a \u0308}] → ae;
[ö {o \u0308}] → oe;
[ü {u \u0308}] → ue;
{$AE} [:Lowercase:] → Ae;
{$OE} [:Lowercase:] → Oe;
{$UE} [:Lowercase:] → Ue;
$AE → AE;
$OE → OE;
$UE → UE;
::Any-ASCII;

// legacy alias, doesn't actually do anything in this case
["de-ASCII"],
false,
true,
);
collection.register_source(
&"und-t-und-latn-d0-ascii".parse().unwrap(),
"# ... ".to_string(),
// the previous transliterator refers to this one by the `Any-ASCII` ID,
// so it's important that the alias is listed here.
["Latin-Ascii", "Any-ASCII"],
false,
true,
);
let t = Transliterator::try_new_unstable(&collection.as_provider(), &collection.as_provider(), &"de-t-de-d0-ascii".parse().unwrap()).unwrap();
assert_eq!(t.transliterate("Käse".into()), "Kaese");
Implementations§
source§impl RuleCollection
impl RuleCollection
sourcepub fn register_source<'a>(
&mut self,
id: &Locale,
source: String,
aliases: impl IntoIterator<Item = &'a str>,
reverse: bool,
visible: bool,
)
pub fn register_source<'a>( &mut self, id: &Locale, source: String, aliases: impl IntoIterator<Item = &'a str>, reverse: bool, visible: bool, )
Add a new transliteration source to the collection.
sourcepub fn register_aliases<'a>(
&mut self,
id: &Locale,
aliases: impl IntoIterator<Item = &'a str>,
)
pub fn register_aliases<'a>( &mut self, id: &Locale, aliases: impl IntoIterator<Item = &'a str>, )
Add transliteration ID aliases without registering a source.
sourcepub fn as_provider(&self) -> RuleCollectionProvider<'_, Baked, Baked>
pub fn as_provider(&self) -> RuleCollectionProvider<'_, Baked, Baked>
Returns a provider that is usable by Transliterator::try_new_unstable
.

Cargo feature.
