Struct IntervalQuery

pub struct IntervalQuery<'a> { /* private fields */ }

A Query builder for specifying the input parameters to the intervals() method in UnicodeVersion.

The builder allows for a more convenient and readable way to specify the input parameters, instead of relying on multiple function arguments.

Examples

use unicode_intervals::{UnicodeVersion, UnicodeCategory};

let intervals = UnicodeVersion::V15_0_0.query()
    .include_categories(UnicodeCategory::UPPERCASE_LETTER | UnicodeCategory::LOWERCASE_LETTER)
    .max_codepoint(128)
    .include_characters("☃")
    .intervals()
    .expect("Invalid query input");
assert_eq!(intervals, &[(65, 90), (97, 122), (9731, 9731)]);

Implementations

impl<'a> IntervalQuery<'a>

pub fn include_categories( self, include_categories: impl Into<Option<UnicodeCategorySet>>, ) -> IntervalQuery<'a>

Set include_categories.

pub fn exclude_categories( self, exclude_categories: impl Into<Option<UnicodeCategorySet>>, ) -> IntervalQuery<'a>

Set exclude_categories.

pub fn include_characters( self, include_characters: &'a str, ) -> IntervalQuery<'a>

Set include_characters.

pub fn exclude_characters( self, exclude_characters: &'a str, ) -> IntervalQuery<'a>

Set exclude_characters.

pub fn min_codepoint(self, min_codepoint: u32) -> IntervalQuery<'a>

Set min_codepoint.

pub fn max_codepoint(self, max_codepoint: u32) -> IntervalQuery<'a>

Set max_codepoint.

pub fn intervals(&self) -> Result<Vec<Interval>, Error>

Find intervals matching the query.

Errors

• min_codepoint > max_codepoint
• min_codepoint > 1114111 or max_codepoint > 1114111

pub fn interval_set(&self) -> Result<IntervalSet, Error>

Build an IndexSet for the intervals matching the query.

Errors

• min_codepoint > max_codepoint
• min_codepoint > 1114111 or max_codepoint > 1114111

Trait Implementations

impl<'a> Clone for IntervalQuery<'a>

fn clone(&self) -> IntervalQuery<'a>

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for IntervalQuery<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq for IntervalQuery<'a>

fn eq(&self, other: &IntervalQuery<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
