Enum mongodb::options::CollationCaseFirst

#[non_exhaustive]
pub enum CollationCaseFirst {
    Upper,
    Lower,
    Off,
}

Setting that determines sort order of case differences during case tertiary level comparisons. For more info, see http://userguide.icu-project.org/collation/customization.

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.

Upper

Uppercase sorts before lowercase.

Lower

Lowercase sorts before uppercase.

Off

Default value. Similar to Lower with slight differences. See http://userguide.icu-project.org/collation/customization for details of differences.
