#[non_exhaustive]#[repr(u8)]pub enum CaseLevel {
Off = 0,
On = 1,
}
Expand description
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)§
This enum is marked as 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”.
