Struct bson::DateTime

source ·
pub struct DateTime(/* private fields */);
Expand description

Struct representing a BSON datetime. Note: BSON datetimes have millisecond precision.

To enable conversions between this type and chrono::DateTime, enable the "chrono-0_4" feature flag in your Cargo.toml.

use chrono::prelude::*;
let chrono_dt: chrono::DateTime<Utc> = "2014-11-28T12:00:09Z".parse()?;
let bson_dt: bson::DateTime = chrono_dt.into();
let bson_dt = bson::DateTime::from_chrono(chrono_dt);
let back_to_chrono: chrono::DateTime<Utc> = bson_dt.into();
let back_to_chrono = bson_dt.to_chrono();

You may also construct this type from a given year, month, day, and optionally, an hour, minute, second and millisecond, which default to 0 if not explicitly set.

let dt = bson::DateTime::builder().year(1998).month(2).day(12).minute(1).millisecond(23).build()?;
let expected = bson::DateTime::parse_rfc3339_str("1998-02-12T00:01:00.023Z")?;
assert_eq!(dt, expected);

§Serde integration

This type differs from chrono::DateTime in that it serializes to and deserializes from a BSON datetime rather than an RFC 3339 formatted string.

e.g.

use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize)]
struct Foo {
    // serializes as a BSON datetime.
    date_time: bson::DateTime,

    // serializes as an RFC 3339 / ISO-8601 string.
    chrono_datetime: chrono::DateTime<chrono::Utc>,
}

let f = Foo { date_time: bson::DateTime::now(), chrono_datetime: chrono::Utc::now() };
println!("{:?}", bson::to_document(&f)?);

Produces the following output:

{ "date_time": DateTime("2023-01-23 20:11:47.316 +00:00:00"), "chrono_datetime": "2023-01-23T20:11:47.316114543Z" }

Additionally, in non-BSON formats, it will serialize to and deserialize from that format’s equivalent of the extended JSON representation of a datetime.

e.g.

let f = Foo { date_time: bson::DateTime::now(), chrono_datetime: chrono::Utc::now() };
println!("{}", serde_json::to_string(&f)?);

Produces the following output:

{"date_time":{"$date":{"$numberLong":"1674504029491"}},"chrono_datetime":"2023-01-23T20:00:29.491791120Z"}

§serde_helpers

The bson crate provides a number of useful helpers for serializing and deserializing various datetime types to and from different formats. For example, to serialize a chrono::DateTime as a BSON datetime, you can use crate::serde_helpers::chrono_datetime_as_bson_datetime. Similarly, to serialize a BSON DateTime to a string, you can use crate::serde_helpers::bson_datetime_as_rfc3339_string. Check out the crate::serde_helpers module documentation for a list of all of the helpers offered by the crate.

use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize)]
struct Foo {
    // serializes as a BSON datetime.
    date_time: bson::DateTime,

    // serializes as an RFC 3339 / ISO-8601 string.
    chrono_datetime: chrono::DateTime<chrono::Utc>,

    // serializes as a BSON datetime.
    // this requires the "chrono-0_4" feature flag
    #[serde(with = "bson::serde_helpers::chrono_datetime_as_bson_datetime")]
    chrono_as_bson: chrono::DateTime<chrono::Utc>,

    // serializes as an RFC 3339 / ISO-8601 string.
    #[serde(with = "bson::serde_helpers::bson_datetime_as_rfc3339_string")]
    bson_as_string: bson::DateTime,
}

§The serde_with-3 feature flag

The serde_with-3 feature can be enabled to support more ergonomic serde attributes for (de)serializing chrono::DateTime from/to BSON via the serde_with crate. The main benefit of this compared to the regular serde_helpers is that serde_with-3 can handle nested chrono::DateTime values (e.g. in Option), whereas the former only works on fields that are exactly chrono::DateTime.

use serde::{Deserialize, Serialize};
use bson::doc;

#[serde_with_3::serde_as]
#[derive(Deserialize, Serialize, PartialEq, Debug)]
struct Foo {
  /// Serializes as a BSON datetime rather than using [`chrono::DateTime`]'s serialization
  #[serde_as(as = "Option<bson::DateTime>")]
  as_bson: Option<chrono::DateTime<chrono::Utc>>,
}

let dt = chrono::Utc::now();
let foo = Foo {
  as_bson: Some(dt),
};

let expected = doc! {
  "as_bson": bson::DateTime::from_chrono(dt),
};

assert_eq!(bson::to_document(&foo)?, expected);
