[−][src]Struct mongodb_h2co3::coll::options::IndexModel
A single index model.
Fields
keys: Document
options: IndexOptions
Methods
impl IndexModel
[src]
impl IndexModel
pub fn new(keys: Document, options: Option<IndexOptions>) -> IndexModel
[src]
pub fn new(keys: Document, options: Option<IndexOptions>) -> IndexModel
pub fn name(&self) -> Result<String>
[src]
pub fn name(&self) -> Result<String>
Returns the name of the index as specified by the options, or as automatically generated using the keys.
pub fn generate_index_name(&self) -> Result<String>
[src]
pub fn generate_index_name(&self) -> Result<String>
Generates the index name from keys. Auto-generated names have the form "key1_val1_key2_val2..."
pub fn to_bson(&self) -> Result<Document>
[src]
pub fn to_bson(&self) -> Result<Document>
Converts the model to its BSON document representation.
