Implementations§

source§

impl CodePointInversionListBuilder

source

pub const fn new() -> CodePointInversionListBuilder

source

pub fn build(self) -> CodePointInversionList<'static>

source

pub fn add_char(&mut self, c: char)

Add the character to the CodePointInversionListBuilder

§Examples
use icu::collections::codepointinvlist::CodePointInversionListBuilder;
let mut builder = CodePointInversionListBuilder::new();
builder.add_char('a');
let check = builder.build();
assert_eq!(check.iter_chars().next(), Some('a'));
source

pub fn add32(&mut self, c: u32)

Add the code point value to the CodePointInversionListBuilder

Note: Even though u32 and char in Rust are non-negative 4-byte values, there is an important difference. A u32 can take values up to a very large integer value, while a char in Rust is defined to be in the range from 0 to the maximum valid Unicode Scalar Value.

§Examples
use icu::collections::codepointinvlist::CodePointInversionListBuilder;
let mut builder = CodePointInversionListBuilder::new();
builder.add32(0x41);
let check = builder.build();
assert!(check.contains32(0x41));
source

pub fn add_range(&mut self, range: impl RangeBounds<char>)

Add the range of characters to the CodePointInversionListBuilder

§Examples
use icu::collections::codepointinvlist::CodePointInversionListBuilder;
let mut builder = CodePointInversionListBuilder::new();
builder.add_range('A'..='Z');
let check = builder.build();
assert_eq!(check.iter_chars().next(), Some('A'));
source

pub fn add_range32(&mut self, range: impl RangeBounds<u32>)

Add the range of characters, represented as u32, to the CodePointInversionListBuilder

§Examples
use icu::collections::codepointinvlist::CodePointInversionListBuilder;
let mut builder = CodePointInversionListBuilder::new();
builder.add_range32(0xd800..=0xdfff);
let check = builder.build();
assert!(check.contains32(0xd900));
source

pub fn add_set(&mut self, set: &CodePointInversionList<'_>)

Add the CodePointInversionList reference to the CodePointInversionListBuilder

§Examples
use icu::collections::codepointinvlist::{
    CodePointInversionList, CodePointInversionListBuilder,
};
let mut builder = CodePointInversionListBuilder::new();
let set = CodePointInversionList::try_from_u32_inversion_list_slice(&[
    0x41, 0x4C,
])
.unwrap();
builder.add_set(&set);
let check = builder.build();

source

assert_eq!(check.iter_chars().next(), Some('D'));
source

pub fn remove_range32(&mut self, range: impl RangeBounds<u32>)

source

pub fn remove_set(&mut self, set: &CodePointInversionList<'_>)

Remove the CodePointInversionList from the CodePointInversionListBuilder

§Examples
use icu::collections::codepointinvlist::{CodePointInversionList, CodePointInversionListBuilder};
let mut builder = CodePointInversionListBuilder::new();
let set = CodePointInversionList::try_from_u32_inversion_list_slice(&[0x41, 0x46]).unwrap();
builder.add_range('A'..='Z');
builder.remove_set(&set); // removes 'A'..='E'

source

let set =
    CodePointInversionList::try_from_u32_inversion_list_slice(&[65, 70])
        .unwrap();
