Enum ComparisonType 

#[non_exhaustive]
pub enum ComparisonType {
    Equal,
    Floor,
    Ceiling,
    Lower,
    Higher,
}

The key comparison applied by a get operation.

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.

Equal

The stored key must be equal to the requested key.

Floor

Return the record with the highest key <= the requested key.

Ceiling

Return the record with the lowest key >= the requested key.

Lower

Return the record with the highest key < the requested key.

Higher

Return the record with the lowest key > the requested key.
