SYNOPSIS #include <mongoc/mongoc.h> typedef struct { bool is_initialized; bool background; bool unique; const char *name; bool drop_dups; bool sparse; int32_t expire_after_seconds; int32_t v; const bson_t *weights; const char *default_language; const char *language_override; mongoc_index_opt_geo_t *geo_options; mongoc_index_opt_storage_t *storage_options; const bson_t *partial_filter_expression; const bson_t *collation; void *padding[4]; } mongoc_index_opt_t; DESCRIPTION This structure contains the options that may be used for tuning a spe- cific index.

This option is silently ignored by the server and unique index builds using this option will fail if a duplicate value is detected.
