}
Expand description
Specifies the fields and options for an index. For more information, see the documentation.
Fields (Non-exhaustive)
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.keys: Document
Specifies the index’s fields. For each field, specify a key-value pair in which the key is the name of the field to index and the value is index type.
options: Option<IndexOptions>
The options for the index.
