All available BSON element types.

Not all element types are representable by the Bson type.

Variants

Double

64-bit binary floating point

String

UTF-8 string

EmbeddedDocument

Embedded document

Array

Array

Binary

Binary data

Undefined

Deprecated. Undefined (value)

ObjectId

ObjectId

Boolean

Bool value

DateTime

UTC datetime

Null

Null value

RegularExpression

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.

DbPointer

Deprecated.

JavaScriptCode

JavaScript code

Symbol

Deprecated.

JavaScriptCodeWithScope

JavaScript code w/ scope

Int32

32-bit integer

Timestamp

Timestamp

Int64

64-bit integer

Decimal128

128-bit decimal floating point

MaxKey

MinKey

Implementations

impl ElementType

pub fn from(tag: u8) -> Option<ElementType>

Attempt to convert from a u8.

Trait Implementations

impl Clone for ElementType

fn clone(&self) -> ElementType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ElementType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<ElementType> for ElementType

fn eq(&self, other: &ElementType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
