Implementations
impl Bson
[src]
pub fn into_relaxed_extjson(self) -> Value
[src]
Converts the Bson value into its relaxed extended JSON representation.
Note: extended json encoding for Decimal128
values is not supported without the
"decimal128" feature flag. If this method is called on a case which contains a
Decimal128
value, it will panic.
pub fn into_canonical_extjson(self) -> Value
[src]
Converts the Bson value into its canonical extended JSON representation.
Note: extended json encoding for Decimal128
values is not supported without the
"decimal128" feature flag. If this method is called on a case which contains a
Decimal128
value, it will panic.
pub fn element_type(&self) -> ElementType
[src]
Get the ElementType
of this value.
