[−][src]Enum mongodb::Bson
Possible BSON value types.
Variants
FloatingPoint(f64)
64-bit binary floating point
String(String)
UTF-8 string
Array(Vec<Bson>)
Array
Document(OrderedDocument)
Embedded document
Boolean(bool)
Boolean value
Null
Null value
RegExp(String, String)
Regular expression - The first cstring is the regex pattern, the second is the regex options string. Options are identified by characters, which must be stored in alphabetical order. Valid options are 'i' for case insensitive matching, 'm' for multiline matching, 'x' for verbose mode, 'l' to make \w, \W, etc. locale dependent, 's' for dotall mode ('.' matches everything), and 'u' to make \w, \W, etc. match unicode.
JavaScriptCode(String)
JavaScript code
JavaScriptCodeWithScope(String, OrderedDocument)
JavaScript code w/ scope
I32(i32)
32-bit integer
I64(i64)
64-bit integer
TimeStamp(i64)
Timestamp
Binary(BinarySubtype, Vec<u8>)
Binary data
ObjectId(ObjectId)
UtcDatetime(DateTime<Utc>)
UTC datetime
Symbol(String)
Symbol (Deprecated)
Methods
impl Bson
[src]
impl Bson
pub fn element_type(&self) -> ElementType
[src]
pub fn element_type(&self) -> ElementType
Get the ElementType
of this value.
pub fn to_json(&self) -> Value
[src]
pub fn to_json(&self) -> Value
: use bson.clone().into() instead
Clones the bson and returns the representative serde_json Value. The json will be in extended JSON format.
pub fn into_json(self) -> Value
[src]
pub fn into_json(self) -> Value
: use bson.into() instead
Consumes the bson and returns the representative serde_json Value. The json will be in extended JSON format.
pub fn from_json(val: Value) -> Bson
[src]
pub fn from_json(val: Value) -> Bson
: use json.into() instead
Consumes the serde_json Value and returns the representative bson. The json should be in extended JSON format.
