Enum IndexKind 

pub enum IndexKind {
    Equality,
    Ordered,
    Array,
    Text,
}

A float as bytes that sort the way the float does. What an index can be asked, and how many keys a document gets at its path.

Variants

Equality

One value at a time. A table from key to posting list and nothing else.

Ordered

One value at a time, or every value between two of them. The same table with a counted B+ tree over its rows.

Array

One element of an array at a time. A document with ["red", "blue"] at the path is filed under both, so a search for either finds it.

Text

One word of a string at a time, folded to lower case. A document with "A red bicycle" at the path is filed under a, red and bicycle.

impl IndexKind

pub fn is_ordered(self) -> bool

Whether this kind can be asked for a range as well as for a value.

pub fn is_multi(self) -> bool
