Enum icu_collator::options::CaseLevel

#[non_exhaustive]
#[repr(u8)]
pub enum CaseLevel {
    Off = 0,
    On = 1,
}

Whether to distinguish case in sorting, even for sorting levels higher than tertiary, without having to use tertiary level just to enable case level differences.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Off = 0

Leave off the case level option. Case differences will be handled by default in tertiary strength.

On = 1

Turn on the case level option, thereby making a separate level for case differences, positioned between secondary and tertiary.

When used together with Strength::Primary, this corresponds to the ECMA-402 sensitivity “case”.

Trait Implementations

impl Clone for CaseLevel

fn clone(&self) -> CaseLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CaseLevel

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

Formats the value using the given formatter.

impl PartialEq for CaseLevel

fn eq(&self, other: &CaseLevel) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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